The Vaisala Indigo520 Supervisor manages up to 100 compatible compact humidity and temperature probes through one host unit. It provides local visibility for the maintenance team and Modbus TCP communication for data centre BMS integration.
Two daisy chains: Up to 50 probes per chain.
5-inch touchscreen: View measurements, probe status and alerts.
Web interface: Supports commissioning and configuration.
Malaysia project support: Contact Seacom for probe selection and installation requirements.
Expected availability: early 2027. Enquire with Seacom for configuration and delivery confirmation.
The Vaisala HMP110 is a high-accuracy humidity and temperature probe designed for demanding equipment integration, environmental chambers, data loggers, incubators and controlled-environment applications.
It provides ±1.5% RH accuracy, a 0–100% RH range, −40 °C to +80 °C temperature measurement, a chemically resistant HUMICAP 180R sensor and analog or Modbus RTU output options.
The Vaisala XMP10 Series comprises compact humidity and temperature probes offering accuracy levels up to ±1% RH and ±0.1 °C for demanding HVAC, data-centre and critical-environment applications.
The probes feature analog or Modbus RTU outputs, a standard M8 connector, an IP65-rated body and compatibility with Vaisala Origo10 modular HVAC transmitters.
The Vaisala HMT370EX provides intrinsically safe humidity and temperature measurement with HMP-series probes. The new DMP370 configuration combines the HMT370EX transmitter with a DMP37X DRYCAP® probe for low-dew-point measurement in hazardous locations.
HMP probes for relative humidity and temperature
DMP370 dew-point measurement from −70 to +10 °C Td/f
Two two-wire 4–20 mA outputs
Certified configurations for hazardous gas and dust areas, up to Zone 0 / 20
Detachable probes and traceable calibration
DMP370 availability: Vaisala plans first deliveries for Q1 2027. Contact Seacom for configuration and project lead time.
The compact Vaisala HM40 Series provides reliable humidity and temperature spot checks for HVAC, construction, warehouses, laboratories, museums and industrial applications.
The Vaisala PTU300 combined barometric pressure, relative humidity and temperature in one transmitter. The series is discontinued and has been replaced by a suitable Indigo520 barometric-pressure configuration with an application-specific HMP probe.
Legacy three-in-one pressure, humidity and temperature transmitter
PTU301, PTU303, PTU304, PTU305, PTU307 and PTU308 variants
Former applications include laboratories, meteorology and semiconductor measurement
Current replacement platform: Indigo520 with barometric-pressure measurement
Humidity probe selected according to mounting and process conditions
Existing wiring, outputs and process connections require migration review
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.
The Vaisala HMW90 Series provides high-accuracy humidity and temperature measurement for demanding indoor HVAC and controlled-environment applications.
Humidity accuracy up to ±1.7% RH
Analog or Modbus RTU output models
Optional display and configurable relay
Replaceable measurement module with calibration certificate
