Summary

  • Available Certified ISO Grade Designs: ISO 7, ISO 8
  • Smart humidity controller provides automatic setpoint control and data logging
  • 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, control, and log data inside desiccator cabinet or glovebox
  • Logs RH, temp, purge on/off, and sensor removal/ attachment
  • Data file is .CSV with ~4MB or 113,000 readings; intervals of 1 SEC, 10 SEC, 1 MIN, 5 MIN, or 1 HR
  • Terra Universal's Smart® 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.
  • Data Logging: Unlike the standard NitroWatch™, the Smart® NitroWatch™ also measures temperature and logs data. This system logs RH, temp, door open/close, purge on/off, and sensor removal/attachment. The system can log months of data depending on the logging interval selected, all of which can be downloaded to a USB flash drive. Plug in USB flash drive and system transfers data in .CSV format. No software required.
  • 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, Smart® NitroWatch™ sensor, automatic RB™ relief/bleed valves (order separately).

Doors - The First Failure Point of a Desiccator Cabinet

Terra’s stainless steel door frames eliminate the need for internal reinforcements, which create particle surfaces and compromise cleaning. Unlike other doors with glue-on anti-bow pieces, Terra’s doors use no adhesives. This eliminates particle traps, sources of outgassing—and extends the strength and service life of the desiccator.
