The Edgetech Instruments Model ELH Series is a series of precision humidity chambers, with NIST traceable accuracies in humidity (±0.5% typical), temperature (±0.1°C) and dewpoint (±0.2°C). The ELH Series consists of a programmable controller for constant precision control and uniformity, and an integrated DewMaster chilled mirror hygrometer for accurate temperature and humidity measurements.
The ELH series offers three standard chamber sizes: 1.5cu.ft., 6cu.ft. and 10cu.ft. Larger volume chambers are also available. All chambers use an environmentally safe non-depleting refrigerant.
The Edgetech Instruments Model DPS3 is a heated dewpoint hygrometer that can measure dewpoints up to 95 °C (203°F) and as low as -35 °C (-31°F). This integrated system includes a microprocessor-based electronics, a chilled mirror dewpoint sensor, a sample flow meter/valve, assorted tubing and fittings all contained in a heated, temperature-controlled NEMA-4 enclosure.
The Edgetech Instruments DewMaster is a fast, multi-function, high precision chilled mirror hygrometer for continuously
monitoring the dew/frost point temperature, parts per million water vapor by volume or percent relative humidity in gas
streams. Based on the primary method chilled mirror measurement technique, it features a user-friendly, easy access sensor, automatic startup, auto-balance, self-diagnostics, analog outputs, serial interface, and alarms. Unlike other dew/frost point sensor types, chilled mirror sensors are easily cleaned and rarely require replacement
The Model 1500 is a drift-free, low maintenance hygrometer featuring high durability, NIST traceable certification, and ease of use. Its primary method chilled mirror sensor provides precision dew/frost point temperature measurement in a robust, transportable package.
Simply attach the sample line, adjust the flow with the integral flow meter and turn on the power. Within minutes you will be collecting field dew/frost point data with the same chilled mirror accuracy of a laboratory standard hygrometer. With a nominal battery life of 12 hours, you will be able to collect data for the entire shift or spot-check your processes for several days without recharging.
