EdgeTech 1500 Battery Dew Hygrometer

The EdgeTech 1500 Battery Dew Hygrometer is a portable, self‑contained chilled mirror dew point measurement instrument designed for accurate moisture analysis of gases in field, laboratory, and industrial environments. Its primary‑method chilled mirror sensor delivers highly reliable and NIST‑traceable dew/frost point readings, providing laboratory‑grade precision outside of a fixed lab setting. The unit is built into a rugged, transportable housing with an integrated sample flow meter and power system that includes a rechargeable battery capable of supporting approximately 12 hours of continuous field operation, making it ideal for extended on‑site use without reliance on external power.

Setup is straightforward: simply connect a gas sample line to the hygrometer, adjust the sample flow using the built‑in flow meter, and power on to begin dew/frost point measurement within minutes. The instrument’s chilled mirror technique minimizes drift and provides stable, repeatable results with low maintenance requirements compared with other moisture measurement technologies.

Optional accessories—such as precision air temperature probes and pressure transducers—can expand functionality to include relative humidity (RH) and parts‑per‑million by volume (ppmv) measurements, offering broader psychrometric analysis. The 1500 supports a range of chilled mirror sensors (e.g., DS or S‑Series options) to match the desired dew point measurement range, and optional outputs like analog (4–20 mA or 0–5 VDC) and RS‑232 enable data logging and integration with external systems.

Engineered for demanding applications where moisture control is critical, the EdgeTech 1500 is widely used for compressed air and dryer performance verification, HVAC and environmental chamber assessments, process troubleshooting, glove box or duct monitoring, refrigerated storage moisture checks, and quality control in manufacturing or calibration settings. Its combination of portability, precision, and ruggedness makes the 1500 a versatile choice for technicians, engineers, and metrology professionals who require accurate dew point data in diverse settings.
