KIN-TEK manufacturers several Span Pac™ H2O models to insure an economical solution to every moisture calibration problem.
Single Oven (Span Pac™ 61-H2O)
The single-oven model can produce moisture concentrations over a 20:1 range within an overall bounds of 0.1 to 10,000 ppm (depending on the permeation tube emission rate and dilution flow rate) in nitrogen and other inert background gases. The standard primary dilution mass flow rate range is 0.25 to 5 lpm. Other flow range options are available.The component flow path features all electropolished stainless steel tubing with heat tracing.A cabinet purge port is available to:
- Purge the cabinet with dry inert gas to minimize outboard-to-inboard contamination from atmospheric moisture when generating low moisture concentrations. Dry nitrogen or zero air is recommended.
- Maintain an acceptable nitrogen level within the cabinet when using hydrogen as the diluent gas to eliminate any possibility of an explosive mixture. The user must supply a continuous controlled flow of nitrogen to the purge port.Single Oven (Span Pac™ 61-H2O)

Dual oven (Span Pac™ 261-H2O)
The dual-oven model is similar to the single-oven model, but can generate concentrations over a 400:1 range depending on selection of permeation tube emission rates.
For both of the above instruments (Single Oven and Dual Oven), a cabinet purge port is available to:
- Purge the cabinet with dry inert gas to minimize outboard-to-inboard contamination from atmospheric moisture when generating low moisture concentrations. Dry nitrogen or zero air is recommended.
- Maintain an acceptable nitrogen level within the cabinet when using hydrogen as the diluent gas to eliminate any possibility of an explosive mixture. The user must supply a continuous controlled flow of nitrogen to the purge port.
