Modulator Valves valves are connected using a manifold to construct a set of doubles, or connected together. The manifolded doubles are sometimes disassembled, the manifold removed, and the left-hand & right-hand modular valve manifold ports are plugged to make two single cylinders. Left and right modular valves are also commonly found in the pairs of single cylinders used with fully closed-circuit rebreathers. Its various designs have deliberate incompatibilities to preclude the possibility of errors when handling different types of compressed gases at differing working pressures. The regulator first stage DIN connector is a male screw type, and instead of clamping on to the outside of the valve, it screws directly into the female DIN outlet of the valve. The sealing O-ring is held in the end of the regulator connector rather than in the face of the outlet.

Moisture Analyzers are used as multichannel analyzer, moisture meter or moisture sensors for absolute moisture analysis in liquids. Moisture analyzers are provided in weather-protective enclosures and explosion proof enclosures.

Moisture Meters measure the moisture content in bulk solids, liquids and gases. Moisture meter requires an analysis of performance specifications and output options. Moisture meters with frequency or pulse outputs use amplitude modulation, frequency modulation or pulse width modulation.

Moisture Calibrator generates moisture content and it included designs like ice bath or a glycol chiller. Small differences in saturation temperature resulted in large differences in moisture content to design the calibrator for ambient temperature. To protect the calibrator from particulates, the upstream gas is passed through a filter and ultra high purity nitrogen is saturated with moisture at a known pressure and temperature. The upstream and downstream saturator pressures are monitored using TH-1 pressure transducers. Most yield monitors have moisture calibration data for numerous crops. Also grain samples are collected for moisture content determination using an accurate moisture meter to insure the proper moisture calibration of the monitor.
