Model 1500 Portable Dewpoint Hygrometer
Self-Contained Chilled Mirror Hygrometer for Fast, Rugged Field Moisture Measurement
Starting at: $4,900
The Edgetech Instruments Model 1500 is a portable, self-contained hygrometer that delivers accurate moisture measurement in gases using a primary method chilled mirror sensor. Housed in a rugged, high-impact case and powered by a 12-hour rechargeable battery, it’s ideal for field technicians who need precision, NIST-traceable data in demanding environments. Setup is quick—just connect the sample line, adjust flow with the built-in flow meter, and power on for lab-grade dew/frost point readings in minutes.
Trusted by calibration and manufacturing teams, the Model 1500 offers fast response, quick dry-down, and long service life. It supports optional temperature and pressure sensors and is compatible with locally or remotely mounted D-Probe and S-Series chilled mirror sensors to meet a wide range of industrial applications.

Frequently Asked Questions
Q: What sensor range options are available for the Model 1500?
A: Range depends on the sensor configuration—from −20°C to +50°C (DS2) down to −75°C to +50°C with the S3 liquid-cooled option.
Q: How long does the battery last for field work?
A: The Model 1500 offers a nominal 12-hour battery life, supporting full-shift field measurements without recharging.
Q: Can the system calculate RH or ppmv?
A: Yes. Add the temperature measurement option for live relative humidity, and a pressure transducer option for live ppmv measurement.
Q: What’s the difference between D-Probe and S-Series sensors?
A: D-Probe sensors are remotely mounted insertion sensors (air cooled, two-stage). S-Series sensors are flow-through sensors available in local or remote configurations with two or three stages.
