Sealed wireless temperature and humidity sensor AR437

Product Description

• radio sensor for temperature and relative humidity designed to operate with recorder AR40x (AR407/AR406)
• portable housing (IP20) adapted for wall mounting, improving the reliability by high resistance to water ingress, dust and surface condensation of vapour inside the unit.
• Radio transmission in ISM 868MHz band, range up to 200 m (open space) - depending on the local radio propagation conditions: type and thickness of walls, doors, etc.
• option of increasing the radio range up to 400 m by activating in other AR43x sensors the function of measurement retransmission (the retransmission requires supplying sensors via the USB port, the network may include up to 3 re-transmitters within AR40x range)
• 7 radio channels enabling independent work seven neighbouring sets of AR40x recorders and related sensors
• measurement of relative humidity (0÷100%RH) and temperature (-30÷80 °C), 2-channel sensor
• high quality digital probe integrated into the housing or external
• option of presenting and recording data in one- (humidity only) or two-channel configuration with up to 16 sensors in a single AR40x recorder
• programmable measurement and update period - from AR40x recorder range: 1 min. to 4 hrs.
• battery power supply (3.6V, AA type), with the batteries replaced by the user
• long operation with a new battery (up to 4 years, at room temperature, with measurement period > 30 min and uninterrupted radio transmission)
• free software provided for displaying recorded results as graphics or text (in AR40x) and for configuring the parameters
• programmable resolution of indications, calibration and alarm parameters, identification number (ID) and other configuration parameters
• parameter configuration via USB serial interface
• high accuracy, long-term stability of measurements and immunity to interferences
• compatibility with RED directive (2014/53/UE)
• measurement accuracy:
  • humidity: ± 3%RH (in the range of 20÷80%RH), ±3÷5%RH (for remaining range)
  • temperature: ± 0.5°C (in the range of 20÷30°C), ± 0.5°C to 1.8°C (for remaining range)
• hysteresis ±1%RH
• long-term stability: <0.5% RH/year
• optionally (charged) - test certificate
• working environment: air and neutral gases, dust-free
