General Description

The HC1000 is a complete, versatile and splash-proof portable combination meter designed with the utmost
precision and simplicity. Measurements of pH, EC and TDS can be easily selected using a membrane keypad on the
front panel.

Conductivity measurements are automatically compensated for temperature changes with a built-in
temperature sensor. The temperature coefficient is fixed at 2%/°C.

HC1000 is a pH/EC/TDS meter designed for simplicity of use in taking pH, mS/cm, ppm and temperature in
the °C scale measurements.

Operation Guide

INITIAL PREPARATION
Each meter is supplied complete with a 9V battery. Remove the battery compartment cover on the back of the
meter and install the battery while observing its polarity.
Connect the probe to the DIN socket on the top of the meter by aligning the pins with the socket and pushing in
the plug.
Always remove the probe protective cap before taking any measurements, and make sure the meter has been calibrated.
Turn the meter on by pressing the On/Off key.

TAKING pH MEASUREMENTS
If theprobe has beenleft dry, soak thetip for 30 minutes to reactivate it.

To take a pH measurement simply submerge the tip (4cm/1½") of the probe into the sample to be tested.

Select the pH mode.

Stir briefly and wait a couple of minutes for the reading to adjust and stabilize.
The display shows the pH value.

If measurements are taken in different samples successively, it is

recommended to rinse (clean) the probe thoroughly to eliminate
cross-contamination. After cleaning, it is recommended to rinse the probe
with some of the next sample to be measured.

TAKING EC/TDS MEASUREMENTS

Immerse the tip of the probe (4cm/1½") into the sample to be tested. If possible, use
plastic beakers or containers to minimize any EMC interference.
Tap the probe lightly on the bottom of the beaker to remove any air bubbles which may be trapped inside the tip.
Select the appropriate measurement range (EC or TDS).

Wait for a couple of minutes for the temperature sensor to reach thermal equilibrium.
The display then shows the measurement automatically compensated for temperature
with the appropriate following indication: “mS” tag indicates the meter is in EC mode,
while “ppm” tag indicates the meter is in TDS mode.

TAKING TEMPERATURE MEASUREMENTS

Submerge the tip (4cm/1½") of the probe into the sample to be tested.

Select the °C mode.

Stir briefly and wait a couple of minutes for the reading to adjust and stabilize.

The display shows the temperature value.

Notes: • If the display shows only a “1” on the far left hand side, the reading is out of range.

It is recommended to clean the probe often.

After measurements have been completed, the instrument should be switched off,
and the probe cleaned and covered with the protective cap.
pH Calibration

For greatest accuracy, frequent calibration of the instrument is recommended. The instrument should be
recalibrated for pH:
a) Whenever the electrode is replaced.
b) At least once a month.
c) After testing aggressive chemicals.
d) Where extreme accuracy is required.
e) Whenever the CAL-CHECK test fails (HI 9813-6 only).
PREPARATION
Pour small quantities of pH 7.00 or pH 4.01 solution into a clean beaker.

To obtain accurate readings, use pH 7.00 if you are going to measure neutral or close to neutral samples, pH 4.01
if you are going to measure acidic samples.
If you need to calibrate to NBS standards, use pH 6.86 instead of pH 7..
PROCEDURE
Connect the probe and switch the meter on, then press the pH
key to display pH measurement.
Remove the protective cap from the probe, rinse and immerse it in the buffer and stir gently.
Wait a couple of minutes for the reading to stabilize.
Take the temperature of the buffer solution, e.g. 10.0°C, as follow: select
the °C mode and read the displayed value.
Adjust the pH calibration dial until the LCD shows the pH value at the
above temperature (see the pH versus temperature chart).
The pH calibration is now complete.
Notes: • The probe should be submerged approximately 4 cm (1½") into the solution. The thermometer
has to be located close to the probe.
If turning the dial the needed value can not be reached, clean the probe (see the “Probe Maintenance” section). If also
after the probe cleaning the value can not be reached, replace the probe.
pH Values at Various Temperatures
For temperature compensation during calibration, please refer to the following chart.
TEMP pH VALUES
ºC ºF 4.01 6.86 7.01

0 32 4.01 6.98 7.13

5 41 4.00 6.95 7.10

10 50 4.00 6.92 7.07

15 59 4.00 6.90 7.05

20 68 4.00 6.88 7.03

25 77 4.01 6.86 7.01

30 86 4.02 6.85 7.00

35 95 4.03 6.84 6.99

40 104 4.04 6.84 6.98

45 113 4.05 6.83 6.98

50 122 4.06 6.83 6.98

55 131 4.08 6.84 6.98

60 140 4.09 6.84 6.98

65 149 4.11 6.84 6.99

70 158 4.12 6.85 6.99

For instance, if the buffer temperature is 25°C, the display should show pH 4.0 or 7.0. If the buffer temperature
is 10°C, the display should show pH 4.0 or 7.0.
EC/TDS Calibration

Accessories needed:
Use 1413 µS/cm = 1.413 mS/cm) EC calibration solution or 1500 ppm TDS calibration solution.
Note: The conversion between EC and TDS is made by a built-in circuit, hence it is requested to calibrate the
meter only in EC or TDS range. The other range is thus automatically calibrated.
PROCEDURE
Pour approximately 4 cm (1½") of a conductivity calibration solution (e.g. HI 7031) into a beaker. If possible,
use plastic beaker to minimize any EMC interference.

Immerse the probe in the solution.

Wait for a couple of minutes for thermal equilibrium to be reached.

Tap the probe on the bottom, then shake it lightly while rotating to make sure no air bubbles remain trapped inside
the probe.

Press the mS/cm (or ppm) key.

Turn the EC/TDS calibration dial until the display shows the EC or TDS reading at 25°C.
Battery Replacement

These meters are powered by a 9V battery that is located on the rear of the instrument.
When battery symbol is empty a low battery condition is indicated.

When the low battery indication appears, only a few hours of working time remains.
It is recommended to replace the battery immediately.
When the battery level is so low that it may cause unreliable measurements, the meter turns off.
Battery replacement must only take place in a nonhazardous area using a 9V alkaline battery.
Unscrew the three screws on the rear of the meter, remove the battery compartment cover and replace the 9V
battery with a new one while observing its polarity.

Make sure the battery contacts are tight and secure before replacing the cover.
Probe Maintenance
PERIODIC MAINTENANCE
Inspect the probe and the cable. The cable used for the connection to the meter must be intact and there must be no
points of broken insulation on the cable or cracks on the probe stem or bulb.
Connector must be perfectly clean and dry. If any scratches or cracks are present, replace the electrode. Rinse off any salt
deposits with water.
CLEANING PROCEDURE
For better accuracy in measurements and to ensure a good performance of the probe, a frequent cleaning is recommended.
For this purpose, soak in Cleaning Solution for 5 minutes.
Note: For particular dirty (as for example protein, oil or grease) see the “Accessories” section for Trace2o specific
solutions.
RECOMMENDATIONS FOR USERS
Before using these products, make sure they are entirely suitable for the environment in which they are used.
Operation of these instruments in residential areas could cause unacceptable interferences to radio and TV
equipment, requiring the operator to follow all necessary steps to correct interferences.
The glass bulb at the end of the electrode is sensitive to electrostatic discharges. Avoid touching this glass bulb at all
times.
During operation, ESD wrist straps should be worn to avoid possible damage to the electrode by electrostatic
discharges.
Any variation introduced by the user to the supplied equipment may degrade the instrument's EMC performance.
To avoid electrical shock, do not use these instruments when voltages at the measurement surface exceed 24 V AC or 60
V DC.
To avoid damages or burns, do not perform any measurement in microwave ovens.

Trace2o reserves the right to modify the design, construction and

appearance of its products without advance notice.
