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.
Dual Purge™ System Diagram
The Dual Purge™ is a variable gas-purge system that switches between "high-flow" and "low-flow" to efficiently and effectively remove and block out moisture and contaminants. Without NitroWatch™, Dual Purge™ does not sense or display RH%. It uses magnetic door sensors to initiate high-flow. When a door is opened or when pressure drops, high-flow activates for a user-specified interval before switching back to an adjustable low-flow setting to conserve nitrogen. With all doors closed, the system maintains an economical "low-flow" to maintain constant positive pressure.
Dual Purge™ and Nitrowatch™ System Diagram
The NitroWatch module connects to a humidity sensor inside the desiccator cabinet and activates the Dual Purge to automatically maintain sub-ambient RH down to 0% RH. When the RH set-point is reached, the system reverts from high-flow to low-flow nitrogen gas to maintain the set-point and conserve nitrogen. When a door is opened, or when the RH climbs above set-point, the system re-activates high-flow to accelerate moisture removal.
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.
