Features & Benefits

Features and Benefits

Critical Environment Solutions

Terra's mission is to help customers in highly regulated industries transform the world with critical environment solutions that improve health, safety, performance, and yields. These environments may comply with stringent UL, ISO, IEST, ASTM and OSHA standards and local requirements.

Stainless Steel Racks for Adjustable Shelf Storage Desiccators

Unlike common chrome-plated hardware, durable electropolished stainless steel racks for adjustable shelf storage desiccators help maintain a contamination-free storage environment. They resist corrosion and chipping/scratching from the sliding removable shelves.

Internal Keyed Steel Drawers

Drawers inside the High-Security Storage Desiccator safe provide secure, fire-safe storage of documents and small valuables. Locking drawers are 4.5” tall.

Locking Chrome Bolts on High-Security Desiccator

One-inch-diameter chrome bolts interlock with recesses built into the safe’s perimeter.

  • Dual Purge™ and NitroWatch™ Work Together to Fully Automate RH Control

    Terra's Dual Purge™ and NitroWatch™ operate in tandem to precisely and automatically control the flow of nitrogen and maintain a preset humidity level (from ambient to 0% ± 1.5% RH), no matter how operating conditions may change.
  • Data Logging with 113,000 Readings at User Defined Intervals

    Terra's Smart® IsoDry® Nitro-Watch™ logs RH, temp, door open/close, purge on/off, and sensor removal/attachment. The max data file size is roughly 4 MB or 113,000 readings. This is approximately 32 hours of data when logging at 1 second intervals, 2 weeks at 10 second intervals, 6 weeks at 30 second intervals, or 12 weeks at 1 minute intervals. When the system reaches the 4MB limit, data begins to wrap, overwriting oldest data with new.
  • Plug & Play Data Logging

    Plug in a USB flash drive to your Smart® IsoDry® Nitro-Watch™ to transfer data in .CSV format. No software required.
