Moisture in Gas Transmitter
Vaisala HPP270 Series Vaporized Hydrogen Peroxide Probes
The Vaisala HPP270 Series provides stable, repeatable measurement for demanding vaporized hydrogen peroxide bio-decontamination processes.
- HPP271 measures vaporized H₂O₂ concentration
- HPP272 adds relative saturation, relative humidity and temperature
- H₂O₂ measurement range from 0 to 2000 ppm
- Accuracy of ±10 ppm or 5% of reading, whichever is greater
- Two 4–20 mA outputs or RS-485 with Modbus RTU
- IP65 stainless-steel construction with Vaisala PEROXCAP® technology
- Compatible with Vaisala Indigo transmitters and Indigo80
Vaisala DM70 Portable Dew Point Meter
The Vaisala DM70 was a portable meter for dew-point spot checks, process measurements and data logging. It is discontinued and replaced for general dew-point work by the Vaisala Indigo80 handheld indicator with a DMP80A or DMP80B probe.
- Legacy DMP74A, DMP74B and SF₆-specific DMP74C probe options
- Direct or sampled measurement in pressurised processes
- Portable numerical and graphical display with data logging
- Current replacement: Indigo80 with DMP80A or DMP80B
- DMP80A for moderate dew points down to −40 °C Td/f
- DMP80B for dry applications down to −70 °C Td/f
Vaisala DPT145 Multiparameter Transmitter for SF6 Gas
The Vaisala DPT145 provides online dew-point, pressure and temperature measurement for SF6-insulated electrical equipment. The model is being discontinued and should not be specified for new projects.
- Measures dew point, pressure and temperature
- Calculates SF6 density, normalised pressure and moisture in ppm
- RS-485 communication with Modbus RTU
- Contact Seacom for availability and replacement assessment
