Humidity-Temperature Indicator A1H

humidity-temperature_indicator_a1h.jpg (8604 octets)Simple to operate and versatile, the A1H combines advanced probe technology with a robust design

  • Digital HygroClip plug-in probe uses accurate, highly stable and durable sensors
  • Measuring range: 0... 100%RH and -10...60°C/14..140°F (-40...85°C/-40...185°F with probe extension cable)
  • Swivel probe base provides for optimum viewing angle of the LC display
  • HOLD fonction facilitates measurements in hard-to-reach places
  • Auto-power-off conserves battery power
  • Operates with 9V alkaline battery or with AC adapter
  • Optional HW3 software permits direct data logging/graphing on a PC or Laptop, data conversions and field calibration of the HygroClip probe
  • Analog voltage outputs for use with a recorder or printer
  • Fully interchangeable HygroClip is replaced in seconds with no loss of accuracy and no calibration

HW3 Software

The HW3 software is used to record data from the A1H to a PC or Laptop. The data can be displayed as a table or as a graph. If so desired, HW3 can also be used to calibrate the HygroClip. Requirements: Pentium 95 Mhz or better, Windows 95/98 or NT, 20 MB free space, 600x800 color monitor, one free COM port.
