Humidity, Temperature, and Barometric Pressure Probe Description

HTP is a multi-parameter, high-accuracy digital probe. Due to its low power consumption, versatile electrical interfacing options, and wide-range power supply, the probe is compatible with a variety of battery operated dataloggers and industrial data acquisition systems. A stainless-steel enclosure in combination with weatherproof electronic circuitries, and durable cable, ensure proper long-term operation even in harsh outdoor and demanding industrial conditions. All primary parameters are sensed by physical sensors. The secondary parameters are calculated, based on values measured by the probe's physical sensors. For optimal results in outdoor applications, it is recommended to install a probe in a solar shield.

Automatic Statistical Logging

Our probes provide continuous environmental statistics collection during uninterrupted power periods. EVVOS HTP continuously updates a set of basic statistical values for every primary and secondary parameter while the unit remains powered. Each statistical record includes minimum, maximum, first, and last measured values, plus the total count of measurements processed. Records update automatically with each new measurement (max sample count: 999,999). Data accumulation resets after power-up. Readouts and manual control of per-parameter statistics are available via protocol commands. For more information, please refer to the User's Manual.
