Humidity and Temperature Probe HMP110

with ±1.5%RH accuracy for demanding volume applications

The Vaisala HUMICAP® Humidity and Temperature Probe HMP110 is a trouble-free and cost-effective humidity transmitter with high accuracy and good stability. The power consumption is low and it has fast startup for battery-powered applications.A rugged polyurethane filled stainless steel body survives also in rough conditions. All models come with a calibration certificate. This probe is suitable for volume applications or integration into other manufacturers' equipment and also for glove boxes, greenhouses, fermentation and stability chambers, data loggers, and incubators.

Three models available:

  • Humidity and temperature probe
  • Temperature only probe with an RS485 interface supporting Modbus RTU protocol
  • Temperature only probe with voltage outputs

The miniature size HMP110 has a measurement range of 0 ... 100 %RH; -40 ... +80°C and the probe incorporates the latest generation HUMICAP® 180R sensor for best stability and high chemical tolerance. The HMP110 has an IP65-classified metal housing.
