Dpstar is a leader in environmental and industrial measurements. Curiosity and innovation are core values in our company. Our extensive knowledge and expertise are materialized in our selection of innovative products. Accurate measurements are essential for healthy indoor air and improving the energy efficiency of buildings. The unique, cutting-edge Dpstar sensor technologies are manifested throughout our versatile range of products. The transmitters have an exceptionally long lifetime and excellent measurement stability, thus being practically maintenance-free. These are among the many reasons why Dpstar’s products are a sustainable choice.

The 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 a 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 are 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.

Benefits

  • Easy Installation
    The probe cable has a screw-on quick connector for easy installation. Different cable lengths and accessories are available.
  • Low current consumption
    HMP110 is suitable for battery-powered applications because of its very low current consumption. It also has a fast start-up time.
  • Several Outputs
    Temperature measurement is a standard feature in the HMP110, with dew point temperature, wet bulb temperature, absolute humidity, mixing ratio, and enthalpy as optional calculated parameters. Three standard voltage outputs are available. An optional RS-485 output with Modbus support is also available.
  • Robust Design
    The stainless steel body of HMP110 is classified as IP65, making it ideal for rough conditions. HMP110 has high chemical tolerance thanks to the
    HUMICAP 180R sensor.
  • Easy Maintenance
    Maintaining measurement traceability is easy using the HMP110R replacement probe. We send you a replacement probe, you detach the old probe and send it back to us. This way the measurement is available at all times without interruptions.
