Summary

  • Available Certified ISO Grade Designs: ISO 7, ISO 8
  • Smart humidity controller provides automatic setpoint control for desiccator cabinet or glovebox
  • Works in tandem with Terra's Dual Purge to maintain sub-ambient RH set-point down to 0% RH
  • Connects to a single sensor to monitor and control RH inside desiccator or glovebox
  • Upgrade to Smart® IsoDry® Nitro-Watch™ for temperature sensing and built-in data logging
  • Terra Universal's IsoDry® Nitro-Watch™ senses and displays the relative humidity level (from ambient to 0% RH) inside a desiccator or glove box within ±1.5% RH. It operates in tandem with Terra's Dual Purge™ System to precisely and automatically control the flow of nitrogen into a desiccator, glove box, or similar enclosure, and maintains a preset humidity level, no matter how operating conditions may change.
  • Programmable logic gives user complete control over warning alarms and other system functions.
  • Automatically controls Dual Purge™ System with high/low flow purges to maintain any relative humidity from 0% RH to room ambient.
  • Application Note: The NitroWatch sensor provides an exact %RH reading in one chamber only. If multiple RB valves are installed and doors are frequently opened, this reading may not be representative of all chambers. For precise chamber-by-chamber monitoring and control in a desiccator cabinet, select Terra's NitroPlex system. For gloveboxes that require greater accuracy and control, Terra's DewWatch™ measures moisture volumes down to 0.5 PPM.
  • Requires: Dual Purge™ unit, NitroWatch® sensor, automatic RB™ relief/bleed valves (order separately).
