3050-SLR for Super Low


Range Moisture Analysis
Quartz-crystal microbalance (QCM)
technology: accurate, reliable, verifiable
and responsive
The 3050-SLR provides an extremely accurate measurement
of trace levels of moisture in a gas through the use of a
quartz-crystal oscillator sample cell. This analyzer brings the
benefits of quartz-crystal technology to a broad spectrum
of low-range moisture measurement applications.

Direct measurement of concentration


The 3050-SLR measures moisture concentration directly
in parts per million by volume (ppmv), parts per million
by weight (ppmw), or mass of water per standard volume
without additional pressure or temperature compensation.
For customers who wish to convert concentration to
dew/frost point, the 3050-SLR can be programmed for a
KEY BENEFITS
live process pressure input or a fixed process pressure. • Most accurate trace moisture measurement
technology available
Accurate and responsive
• Fast response to changing moisture levels
The accuracy of the 3050-SLR is ±0.03 ppmv or ±10%
of reading, whichever is greater, over the calibrated • Specific to moisture in most applications
range of 0.1 to 100 ppmv. The design of the 3050-SLR • Rugged sensor
enables a speed of response that is far superior to other
analyzers, while consuming as little as 150 standard
cubic centimeters per minute (sccm) of sample gas. The APPLICATIONS
reliability and stability of the QCM sensor eliminates the
need for routine factory recalibration requirements. • The 3050-SLR is specifically designed to
monitor trace moisture levels
On-line verification ability
The 3050-SLR is equipped with the ability to self-verify
its accuracy and sensitivity to moisture. This can be done KEY MARKETS
on a programmed schedule, or whenever necessary. With
a built-in zero module and internal moisture generator, • Petrochemical
the 3050-SLR provides data you will have confidence in. If • Natural gas

calibration automatically. If a severe calibration problem • Chemical
exists, the analyzer will provide an alarm.

Moisture Analysis PRODUCT DATA SHEET

PERFORMANCE SPECIFICATIONS
Technology QCM

Range 0.1 to 100 ppmv. Readout capability in ppmw, lb/mmscf, mg/Nm3, and dew point temperature in °C or °F (requires process pressure
as an input)

Reference gas Continuously produced using actual sample gas

Online verifications Internal moisture source with NIST-traceable calibration enables on-demand verification of analyzer accuracy and responsiveness
without uninstalling the analyzer. Verification function can be triggered remotely with a voltage signal

Accuracy ±0.03 ppmv or ±10% of reading from 0.1 to 100 ppmv, whichever is greater

Reproducibility ±0.015 ppm or ±5.0% of reading, whichever is greater

Limits of detection 0.1 ppmv

Moisture generator 1.0 ppmv nominal, calibration is NIST traceable

Reliability No routine factory calibration required due to highly stable and reliable nature of QCM sensor

QCM response time Near real time. Computer-enhanced response, which may lead to errors, is not required to obtain quick wet-up or dry-down response

Sensitivity 0.01 ppmv or 1% of reading, whichever is greater

Allowable inlet pressure 1.38 to 3.45 Bar (20 to 50 psi) gauge (up to 200 Bar (3000 psi)) with optional pressure reducer; analyzer performance is independent
of process pressure

Exhaust pressure 0 to 1 Bar (0 to 15 psi)

Sample gas temperature 0 to 100°C (32 to 212°F); analyzer performance is immune to changes in sample gas temperature
