DC V/A to DC V/A Isolated Transducer TZ-1XA TZ-5XA

The Vaisala DRYCAP® Dew Point and Temperature Probe DMP5 measures humidity directly in hot industrial processes with a long stainless-steel probe and adjustable installation depth.

• Direct in-line measurement at process temperatures up to +180 °C
• Dew point measurement range from −40 to +100 °C Td/f
• Long probe reaches through insulation and thick process walls
• Built-in Modbus RTU or integration with Vaisala Indigo transmitters
• Connect to Indigo80 for portable display, diagnostics, configuration and field calibration

The Vaisala HMT120 and HMT130 provide accurate, stable humidity and temperature measurement for cleanrooms, laboratories, data centres and demanding HVAC applications.

Product transition: HMT120/HMT130 are expected to be phased out. For new projects, the Vaisala Origo10 is the recommended replacement platform.

• Humidity accuracy up to ±1.5% RH
• HMT120 loop-powered 4–20 mA output
• HMT130 voltage outputs, RS-485 and relay
• Interchangeable fixed or remote measurement probe
• Origo10 recommended for new installations

The Vaisala GMD20 Series was designed for carbon-dioxide measurement inside ventilation ducts and demand-controlled ventilation systems.

• Discontinued legacy product; not recommended for new projects
• Nominal CO₂ measurement range from 0 to 2000 ppm
• GMD20 without display and GMD20D with local display
• 0–20 mA, 4–20 mA and 0–10 V analogue outputs
• Optional relay or LonWorks® interface on applicable configurations
• IP65 electronics enclosure for duct installations
• Use Vaisala GMD110 for new installations

MSR gas detection systems continuously monitor combustible, toxic and refrigerant gases, generate local or central alarms and interface with ventilation, shutdown and building-management systems.

• Gas-specific fixed detectors for commercial and industrial applications
• Compact controllers for small systems and networked controllers for larger sites
• Analogue, relay, RS-485 and Modbus integration options
• Local displays, warning indicators, sounders and beacons
• Solutions for general areas and certified hazardous areas
• Applications include refrigeration plants, laboratories, garages and process facilities

The Vaisala HM70 was a handheld meter for humidity and temperature spot checks, field measurements, data logging and verification of installed Vaisala instruments. It is discontinued and replaced by the Vaisala Indigo80 handheld indicator with an HMP80 probe.

• Legacy MI70 handheld indicator with HMP75, HMP76 or HMP77 probe
• Relative-humidity measurement from 0 to 100 %RH
• Probe-dependent temperature measurement from −70 to +180 °C
• Numerical and graphical display with portable data recording
• Current replacement: Indigo80 with HMP80N or HMP80L
• HMP80N for general measurements; HMP80L for extended temperature reach

The Vaisala GMP343 is a rugged, high-accuracy carbon-dioxide probe for outdoor monitoring, ecological research, soil respiration, plant-growth chambers and demanding OEM applications.

• Selectable CO₂ ranges from 0–1000 ppm to 0–2%
• Diffusion-aspirated or flow-through sampling models
• Accuracy up to ±(3 ppm + 1% of reading)
• Temperature, pressure, humidity and oxygen compensation
• RS-232, RS-485, 4–20 mA, 0–2.5 V or 0–5 V outputs
• Raw and numerically filtered measurement data
• IP67 probe housing with the cable connected
• Compatible with MI70 for portable display and logging

The Vaisala HMP1 is a high-accuracy, interchangeable humidity and temperature probe for indoor spaces. It connects directly to an Indigo200 or Indigo300 transmitter to create a compact wall-mounted measurement system.

• Humidity accuracy up to ±1.0% RH
• Temperature accuracy up to ±0.2 °C
• 0–100% RH and −40 to +60 °C measurement ranges
• Modbus RTU and full Vaisala Indigo compatibility
