Precision Chilled Mirror Hygrometers
Stationary chilled mirror hygrometers for labs and process lines that need a NIST-traceable reference measurement, not just a spot reading.

CM10 – Economical Chilled Mirror Hygrometer
Low-cost, NIST-traceable chilled mirror hygrometer for duct, wall, pipe, or OEM installations.

DewTran® II Chilled Mirror Hygrometer
Multi-mount chilled mirror hygrometer measuring dew point, temperature, RH, or barometric pressure.

DewTran® Precision Hygrometer
Patented chilled mirror technology delivering NIST-traceable dew point, temperature, and RH readings at a lower cost.

DewTran LC Precision Hygrometer
Chilled mirror hygrometer measuring dew point plus optional temperature and barometric pressure; wall, duct, or pipe mount.
Portable Dew Point Meters
Battery- or AC-powered meters built for spot checks and field measurement away from a fixed installation.

RO-PDM Portable Dew Point Meter
Portable dew point meter measuring -60°C to 20°C with AC or battery power and a removable, chemical-resistant sensor.
Dewtran II-PDM Portable Chilled Mirror Hygrometer
Battery-powered (48-hour runtime) portable chilled mirror hygrometer with data logging. (Product photo not yet in the media library — worth adding one.)
Humidity & Dew Point Transmitters
Fixed-installation transmitters for continuous humidity, temperature, and dew point monitoring.

RO120-W Precision Transmitter
Wall/duct-mount transmitter combining humidity, temperature, dew point, and barometric pressure with interchangeable ±1% sensor tips.

RO120 Precision Transmitter
Measures humidity, temperature, barometric pressure, and dew point from -40°C to 120°C in a chemical-resistant design.

HDR200
Configurable dew point or relative humidity transmitter with 4-20mA or RS232 output and °C/°F selection.
Trace Moisture Analyzers
Analyzers built for ppm-level moisture detection in process gas applications.

TMA-2100 Trace Moisture Analyzer
Measures trace moisture down to ppm levels with ±0.2°C accuracy via 4-20mA output.

PLMa Loop-Powered Moisture Analyzer
Nanosensor-based, loop-powered (4-20mA) trace moisture analyzer for industrial process applications.
Dew Point Calibration Equipment
Reference equipment for calibrating other dew point and humidity instruments.

PPMG101 Dew Point Generator
Precision moisture generator that creates controlled dew point levels for calibrating chilled mirror hygrometers.
Oxygen & Dual-Parameter Analyzers
These two are primarily oxygen instruments that also read moisture — worth double-checking whether they belong here or under Gas Analyzers.

Oxymaster II
Simultaneously measures oxygen and moisture at trace levels (0-10,000 ppm) using electrochemical sensors.

Oxymaster 16TW
Menu-driven trace oxygen analyzer for aqueous environments with touchpad control and a large LCD display.
