Dpstar is a leading supplier of environmental measurement sensors for temperature, relative humidity, pressure, dew point, CO2, and other environmental condition monitoring for industrial process application and research. Since the ’90s, we earned a reputation as a trusted partner to our clients through our commitment and dedication. We are an authorized distributor and supplier of measuring sensors solutions from renowned manufacturers Vaisala. Vaisala is a global leader in environmental and industrial measurement. Building on 80 years of experience, Vaisala provides observations for a better world. Vaisala is a reliable partner for customers around the world, offering a comprehensive range of innovative observation and measurement products and services.

The HUMICAP HMT120 and HMT130 transmitters are suitable for cleanrooms, museums, laboratories, and data centers. Maintaining measurement traceability is easy due to field exchangeable intelligent measurement probes. These can be exchanged with minimal downtime and process disturbance. The humidity parameter options available are relative humidity, dew point/frost point, wet bulb temperature, enthalpy, absolute humidity, mixing ratio, vapor pressure, and saturation vapor pressure. The HUMICAP Humidity and Temperature Transmitters HMT120 and HMT130 incorporate the HUMICAP technology with humidity sensor HUMICAP 180R. Two options are available: 2-wire loop-powered or 3-wire voltage output configurations. The HMT120/130 is resistant to dust and most chemicals. The devices can be mounted outdoors using an installation kit and the Radiation Shield DTR502B.

Benefits

• Performance
  The HMT120 and HMT130 transmitters incorporate Vaisala HUMICAP humidity sensor technology that measures relative humidity accurately and reliably. HUMICAP sensors are resistant to dust and most chemicals. The HMT120 and HMT130 transmitter enclosure is optimized for use in cleanrooms. The smooth surface of the enclosure makes it easy to clean and the enclosure material is chosen to tolerate purifying agents. Furthermore, cabling can be done through the back wall of the transmitter.
• Interchangeable Probe
  The HMT120 and HMT130 transmitters use a fully interchangeable relative humidity probe. The probe can be easily removed and replaced with a new one without having to adjust the transmitter, which allows for an easy and quick recalibration of the transmitter. The probe can be adjusted using one of the handheld meters as a reference. Also available is a constant output probe with fixed RH and T output for convenient inspection of the monitoring system and signal transfer line.
• Available Options
  The HMT120 and HMT130 transmitters are available as wall-mounted or with a remote probe. For high-temperature applications or where space is limited, the remote probe is ideal. The optional LCD display shows the measurement results of selected parameters in selected units. The parameters are displayed simultaneously on two separate rows on the display.
