Portable calibration unit gives precise frequency and time signals in all situations where conventional laboratory instrumentation cannot be used. Retains accurate time and frequency during long periods of field use due to calibration via GPS and high quality internal oscillator. It consumes low power for long battery life between recharges. It has a unique oscillator attitude sensing and compensation for optimal frequency stability. The rugged design and construction of this unit is for use in all industries and environments.

Portable cartridge dust collectors are another commonly used type of dust collector. Unlike baghouse collectors, in which the filtering media is woven or felt bags, this type of collector employs perforated metal cartridges that contain a pleated, nonwoven filtering media. Due to its pleated design, the total filtering surface area is greater than in a conventional bag of the same diameter, resulting in reduced air to media ratio, pressure drop and overall collector size. Cartridge collectors are available in single use or continuous duty designs. In single-use collectors, the dirty cartridges are changed while the collector is off. In the continuous duty design, the cartridges are cleaned by the conventional pulse-jet cleaning system. These dust collectors always includes a steel enclosure containing porous filter media that separate fine dust particles from a flowing stream of dirty air. The most common filter media used in collectors are filter bags and cartridges. Dust particles build up on the outside of the media and form a coating called dust cake. It is this layer that does the actual job of filtering fine particles. As the cake builds up, the pressure drop across the filter bag rises.

Portable charging cylinders are used for accurate refrigerant charging. Its scale and precision valve allow for accurate charging. It features pressure gauge, removable stand, scale with reflective guard, refrigerant scale and purge & relief valve.

Portable chemical agents detectors are portable chemical contamination control device. It is used to detect chemical agents in the form of vapor or aerosols. It is suitable for military use in rough conditions: fast turn on, immediate identification and measurement, single-handed operation, simplicity of use, ability to be turned off without precautions. It also detects the atoms of phosphorus and sulfur.
