Dew Point Meter for Refrigerant Dryers

The Vaisala DRYCAP® Dewpoint Transmitters DMT345 and DMT346 are designed for humidity measurement in industrial drying applications with particularly high temperatures. The high temperature tolerance of the sensor allows direct measurement from hot process without the need for a sampling system and sample conditioning. The wide dynamic rage of the measurement in DMT345 and DMT346 is unique: Measurements can be made from -40 °C frost point up to +100 °C dew point, with dry-bulb temperatures ranging up to 350 °C.

The Vaisala HUMICAP® Dewpoint Transmitter DMT132 is an affordable dew point measurement instrument designed to verify the functionality of refrigerant dryers.

The Vaisala DM70 Hand-held Dew point Meter measures dew point temperature accurately in a wide measurement range: from -60ºC to +60ºC. DM70 incorporate Vaisala's advanced DRYCAP technology, which enables reliable and high performance dew point measurement. The probe withstands condensation and also measures directly in pressurized spaces. It also has a versatile and easy-to-use menu based user interface and clear graphical LCD display with data-logger function. It can also be used as a tool for reading the output of fixed Vaisala dew point transmitters like DMT340 It has a truly fast response time between start-up from ambient conditions to low and high process dew points.

Also suitable for measuring dryness of SF₆ gas

The Vaisala 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.

DPT145 Overview

- 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

Miniature size dew point transmitters DMT143 and DMT143L are ideal choices when you want to measure dew point accurately in small compressed air dryers, plastic dryers, additive manufacturing and other OEM applications. They are easy to integrate and can be used in Vaisala DM70 hand-held. The long version has replaced the DMT242.

The Vaisala DRYCAP® Dewpoint Transmitter DMT152 is designed for measuring low dew point in OEM applications, even down to -80°C. The excellent long-term stability and reliability of its performance is based on the latest DRYCAP® polymer sensor technology. The DMT152 is an ideal choice for industrial applications where it is necessary to control very low humidity. DMT152 is an ideal choice for the semiconductor industry, air and plastics dryers, glove boxes, dry chambers, pure gases, additive manufacturing, high voltage circuit breakers and other applications where it is critical to control humidity with high accuracy. he DMT152 measures accurately and reliably also in the challenging combination of low humidity and hot air, which is typical in plastics drying.

The Vaisala DTM152 is designed for measuring low dew point in OEM applications, even down to -80 °C.
