The cross flow modulation type, infrared-absorption technology eliminates the need for adjusting optical alignment.
For the user, this means very stable and sensitive (5 ppm F.S.) measurements.

The APMA-370 uses an AS-type interference-compensating detector, and a purified reference gas. The reference gas is generated by purging the sample through an oxidation process, where an oxidizing catalyst burns the CO to CO2. These features eliminate interference from other elements, resulting in highly accurate measurements.

TECHMARK's fixed gas detection systems are available as easy to operate single point units or as larger systems with several hundred transmitters. These multiple point systems consist of controllers and transmitters that communicate with each other. The transmitter changes the measured gas concentration to an electrical signal which is transfered to the controller. The controller shows the gas concentration in a display and immediately activates alarming devices in case of a gas leak. Advanced features such as data logging or online data transmission allow the user to easily monitor ambient changes in the environment. The Stand Alone unit is a combination of both transmitter and controller.

Gastec gas detector tubes are thin glass tubes with calibration scales printed by which you can directly read concentrations of the substances (gases and vapors) to be measured. Each tube contains detection reagent(s) that are especially sensitive to the target substance and quickly produces a distinct layer of color change. The tubes are hermetically sealed.

TECHMARK's portable instruments are the smallest measuring instruments for personal safety. They offer more safety through easy operations. Portable instruments are divided into two different categories:
- Single-Gas Detectors, for detection of one gas
- Multi-Gas Detectors, for detection of several gases at a time

Turbidity refers to the concentration of undissolved, suspended particles present in a liquid. This determination of clarity in water is important in many manufacturing operations such as beverage producers, food processors and potable water treatment plants Turbidity is measured in Nephelometric Turbidity Units.

Electrical Conductivity (EC) meters measure the capacity of ions in an aqueous solution to carry electrical current. As the ranges in aqueous solutions are usually small, the basic units of measurements are milliSiemens/cm (mS/cm) and microSiemens/cm (µS/cm).

DO stands for Dissolved Oxygen, which is the measure of amount of gaseous oxygen (O2) dissolved in a solution. In theory, the amount of DO in a solution is dependent on 3 factors, namely temperature, salinity and atmospheric pressure. The measurement of DO requires a special DO electrode that is made up of an anode, a cathode, electrolyte solution and a gas permeable membrane.

The APPA-365 is capable of simultaneously measuring three air pollutants (benzene, trichloroethylene, and tetrachloroethylene) generated through automotive and factory exhaust emissions that are known to pose a high risk to human health. Measurement is performed in 10-minute cycles, allowing the accurate detection of subtle density changes. In addition, its ease of operation and ability to produce stable measurements over the long term make the equipment well-suited to air-pollution monitoring.

Concentrations of nitrogen and phosphorus have been regulated in order to prevent over-abundance of nutrients in enclosed sea areas. Since the proportion of environmental standards attained is low, in reaction to the over-abundance of nutrients in enclosed sea areas, the 2000 fifth water quality total amount regulations considered all-round policies on nitrogen and phosphorus as well as COD. Our equipment for automatically measuring total nitrogen and total phosphorus allows for compliance with these total amount regulations. We have realized high-accuracy measurements, low cost, and lower maintenance displaying stability over a long period of time. Features

Rechargeable battery operated. Robust. Strong gas pump.
