Liquid Filled Explosion Proof Thermometer with MicroSwitch ES-UT

For use up to zone 0 and 20

The intrinsically safe Vaisala  HMT370EX is the ideal solution for use in hazardous areas up to zone 0 and 20. In addition to measuring relative humidity and temperature, the transmitter outputs also other humidity parameters: dew point temperature, wet-bulb temperature, absolute humidity, mixing ratio, water concentration, water mass fraction, water vapor pressure, and enthalpy. Special models for moisture in oil and jet fuel measurements are available.

Typical applications include fuel storage tanks, manufacturing of chemicals, pharmaceuticals and food, biogas production' paint booths and any other industry or process where intrinsically safe humidity or moisture in oil measurement is required. 

This next-generation HMT370EX transmitter replaces the long-running HMT360 transmitter series.
The HMT370EX offers several probe options for different applications:

• HMP371 - for wall mounting
• HMP373 - for confined spaces
• HMP374 - for pressurized spaces
• HMP375 - for high temperature
• HMP377 - for high humidity
• HMP378 - for pressurized pipelines

Models for measuring moisture in oil and jet fuel:

• HMP378F - for moisture in oil
• HMP378H - for JET A-1 fuel

The Vaisala Indigo, Indigo 510, Indigo 520 transmitter has 4 analog channels that can be configured to mA or voltage type and 2 configurable relays. The Vaisala Indigo510 has 2 analog channels. Any of the output parameters from the connected probes can be assigned to control the analog channels and relays. Digital output protocol is Modbus TCP/IP over Ethernet. Besides Modbus TCP/IP, the transmitter's Ethernet connection provides a web interface and cyber-security that meets the modern standards

The touchscreen display provides local data visualization and easy access to probe configuration. The transmitter also extends the options for connectivity, supply voltage and wiring, compared to using just a smart probe. It also provides mechanical support when wall-mount probe installation is preferred.​ Rugged IP66- and NEMA4-rated  metal enclosure ensures reliable performance even in the harshest conditions.

The Indigo-compatible smart probes include humidity probes (HMP1, HMP3, HMP4, HMP5, HMP7, HMP8 and HMP9), dew point probes (DMP5, DMP6, DMP7 and DMP8),  carbon dioxide probes (GMP251 and GMP252), moisture in oil probe (MMP8), temperature probe (TMP1), and vaporized hydrogen peroxide probes (HPP270). The Indigo520 is also compatible with MHT410 Moisture, Hydrogen and Temperature Transmitter for power transformer online monitoring

The Indigo520 dual-probe support allows simultaneous measurements with two Vaisala Indigo-compatible probes for humidity, temperature, dew point temperature, carbon dioxide, vaporized hydrogen peroxide, and moisture in oil measurements. If you need just one probe, the Indigo510 is an ideal choice.

EDL offers a complete line of stirred liquid bath calibrators for temperatures from –40 °C up to 550 °C. The Ultra Bath has the highest stability and uniformity possible in any bath. We offer three standard bath models based on the specified temperature range.

The Vaisala HMT140 wireless data logger is designed for humidity, temperature and analog signal monitoring in warehouses, freezer and cryogenic farms, laboratories, blood banks and many other life science applications

The Vaisala HMT140 incorporates Vaisala HUMICAP® technology to measure relative humidity and temperature accurately and reliably. The Vaisala HUMICAP sensor is resistant to dust and most chemicals. Alternatively, the Vaisala HMT140 can connect to Resistance Temperature Detectors (RTDs), Voltage, Current and Contact sensors, making the Vaisala HMT140 the most versatile Vaisala data logger for life science applications.

Vaisala Indigo200 Series host devices are part of Vaisala Indigo product family and intended for Vaisala's intelligent, stand-alone humidity probes (HMP1, HMP3, HMP4, HMP5, HMP7, HMP8 and HMP9), dew point probes (DMP5, DMP6, DMP7 and DMP8), temperature probe (TMP1), CO2 probes (GMP251 and GMP252), moisture in oil probe MMP8, as well as our vaporized hydrogen peroxide probe series HPP270: including HPP271 to measure hydrogen peroxide vapor (ppm), or the HPP272 to measure hydrogen peroxide vapor (ppm), temperature, and humidity (relative humidity and relative saturation). The HPP272 probe includes other calculated parameters such as dew point and vapor pressure measurements..

Looking for a transmitter with a metal enclosure? See Indigo500 series with dual-probe support and many more additional features.

Typical applications for the Indigo200 include industrial and compressed air drying, life science incubators, hatchers and setters, greenhouses, cold storage & refrigeration, food transportation, CO2 safety, hydraulic and lubrication oil monitoring, demanding HVAC such as animal shelters, swimming pools, parking garages, and facilities using vaporized hydrogen peroxide decontamination.

Vaisala Indigo 200 allows for easy evaluation and visualization of data, also wirelessly. The installation is uncomplicated, which saves time. Watch video on how to install Indigo201 and configure analog outputs. Also the probe types are interchangeable reducing downtime. The enclosure with an IP65 classification is safe for harsh environments and resistant to dust and most chemicals. The smooth surface of the enclosure makes cleaning easy.

EDL's Comparison Cryostat Calibrator (CRYO-CAL-2) is the most trusted cryogenic calibration device available on the market. This passively cooled cryostat allows the user to safely and affordably calibrate a range of temperature measurement devices from 77K (-196 °C) up to 0 °C. 

The Vaisala Dewpoint, Pressure and Temperature Multiparameter Transmitter DPT145 for SF6 Gas is a unique innovation that enables online measurement of dew point, pressure, and temperature. It also calculates four other values, including SF6 density. The DPT145 is especially well suited for integration into OEM systems.

- First transmitter to offer online measurement of seven SF6 parameters in one unit
- Measured parameters: dew point, pressure, temperature
- Calculated parameters: SF6 density, normalized pressure, dew point in atmospheric pressure, ppm
- Saves time and money across the board, from investment and installation to operation and servicing
- More reliable assessment of the condition of SF6 insulation due to online measurement
- Long calibration interval of years

The Vaisala HM40 is a compact, robust and affordable hand-held meter for various portable measurement applications.
