Recorder of temperature and humidity AR236.B

Product Description

• registration of humidity and temperature of air or other neutral gases with display of measurements
• configurable architecture enabling use in many fields and applications (for industrial, office and residential environments, inside and outside buildings, e.g. warehousing, production, transport, food sector, pharmacy, medicine, gardening, laboratories and others)
• high quality and accuracy digital relative humidity (%RH) and temperature (°C/°F) sensor with a protective filter (measuring probe integrated with the casing or external one on the cable)
• portable housing (IP65) adapted for wall mounting, improving the reliability by high resistance to water ingress, dust and surface condensation of vapour inside the unit
• recording measured values and events in a standard text file stored in the internal memory in FAT system, with access via the USB port
• battery power supply, with the battery replaced by the user
• operation with a new battery up to 15 years (depending on the mode and working conditions)
• two-line readable LCD display with icons and measuring units, showing measured values, operating and memory status of the device, battery level and other diagnostic messages
• the possibility of presenting current measurements (relative humidity and/or temperature), calculated values (dew/frost point [°C/°F] and absolute humidity [g/m3]), measurement statistics (maximum, minimum, average) and clock, available HOLD function (stopping measurements and records)
• internal clock with the possibility of precise correction of real time counting
• F button for quick selection of one of the programmed functions: date and time display, memory status, measurement statistics, measured or calculated values, START/STOP button blocking, alarm memory clearing, switching on/off the Bluetooth wireless communication (BLE, optional equipment)
• programmable function of START/STOP button: measurement refresh only, start/stop or pause/resume of recording (with or without HOLD function), presentation of memory status (recording method, number of occupied memory and how long will it be enough for)
• a wide range of ways to start recording (continuous, limited by date and time, periodic daily, only during an alarm or manually controlled with the START/STOP button)
• included free software (for Windows 7/8/10) enabling reading and graphical or text presentation of recorded results (ARSOFT-LOG) and configuration and copying of device parameters (ARSOFT-CFG), updates available on the website
• the option to readout files with recorded measurements in spreadsheets such as Microsoft Excel or OpenOffice Calc
• programmable types of alarms for humidity and temperature (below or above the threshold with hysteresis, inside band or out of band), intensity, alarm memory and time of insensitivity after resetting alarms memory
• alarm signalling with pulsating LED diodes and sounds (built-in low-volume buzzer)
• programmable displayed values, recording and  alarms options, and other configuration parameters, such as zero calibration of the measured quantity, type of thermometric scale (Celsius [°C] or Fahrenheit [°F]), indications resolution, identification number (ID), state of the BLE interface, etc.
• available protection against unauthorized data copying and modification (programmable password)
• measurement range 0÷100%RH, -30÷80°C
• measurement accuracy:
  • humidity: ±2%RH 
  • temperature: ± 0.3°C
• hysteresis ±0.8%RH, long-term stability: <0.5%RH/year
• response time (63%): 8s (airflow > 1m/s)
• measuring and recording period: programmable from 5 seconds to 8 hours
• communication interface: USB (for communication with the PC) or Bluetooth (read only via Sensirion MyAmbience apps for  Android and iOS)
• saving up to 94 thousand of measurement results
• power supply: lithium battery 3.6V AA (R6), 2450mAh
• operating temperature range: -20÷70°C
• optionally (charged) - test certificate
• REPLACES OLDER RECORDERS AR235, AR236 AND AR238
