[. . . ] www. vaisala. com HMM210 Series Humidity Modules for Environmental Chambers relative humidity and temperature or dewpoint measurement with various configurations. All modules have microprocessor based electronics and are equipped with analog or digital outputs. Unique warmed probe The warmed probe and composite sensor, available on the dewpoint probe configuration, is warmed to always remain a few degrees higher than ambient. [. . . ] Calibration certificate included The Vaisala HUMICAP® Humidity and Temperature Module Series HMM210 are designed for OEM type applications needing humidity or dewpoint measurement in demanding environments, e. g. in environmental chambers growth chambers and incubators. Vaisala HUMICAP® Sensor and chemical purge option The HMM210 modules use Vaisala HUMICAP®180R sensors for best possible stability. In conditions of extraordinary high levels of chemicals and cleaning agents, chemical purge is available as an option. With chemical purge, contaminants are evaporated from the sensor and performance is returned to normal. Demanding applications The HMM210 modules are optimized for harsh environments with both high humidities and a wide temperature range. In addition, the modules remain accurate and reliable under extreme conditions where a combination of high humidity and rapidly changing temperature can result in condensation on the sensor head. They provide either Technical data Relative Humidity Measurement range Accuracy (including non-linearity, hysteresis and repeatability) 0 . . . +158 °F) Sensor protection (standard) stainless steel sintered filter Connections screw terminals for 0. 5 . . . 1. 5 mm2 wires Response time (90 % at +20 °C/+68 °F) in still air (with sintered filter) 60 s Typical temperature dependence of electronics 0. 02 %RH/°C (0. 02 %RH/°F) Humidity sensor HUMICAP®180R Power Supply Operating voltage 10 . . . 35 VDC In modules with analog outputs the supply range depends to a certain extent on the selected output range.
