Leak testing equipment is used to measure the escape of liquids, vacuum or gases from sealed components or systems.
Liquid Leak Detectors
Liquid leak detectors sense when a liquid is leaking from a pipe, tank, or other receptacle.
Moisture Meters
Moisture meters are used to measure the moisture content in bulk solids, liquids and gases.
Oil in Water Monitors
Oil in water monitors are used to detect the presence of hydrocarbons in water.
Oil Sensors and Analyzers
Oil sensors and oil analyzers are used in automotive or industrial machinery applications to sense oil levels, and check for contamination, and particulates, viscosity and/or temperature.
Opacity Sensors and Instruments
Opacity sensors and instruments measure the amount of light transmitted through a sample.
Oxidation Reduction Potential (ORP) Electrodes
Oxygen reduction potential (ORP) electrodes are analytical sensors for measuring oxidation-reduction potential (ORP).
Oxidation Reduction Potential (ORP) Instruments
Oxidation reduction potential (ORP) instruments measure or monitor ORP in solution.
pH Electrodes
pH electrodes are analytical sensors for measuring potential of hydrogen (pH), the negative logarithm of the hydrogen ion activity in solution.
pH Instruments
pH instruments are used to measure or monitor potential of hydrogen (pH) in a solution.
pH Transmitters
pH transmitters provide electrical outputs that are proportional to potential of hydrogen (pH) inputs.
Plant Growth Chambers
Plant Growth Chambers are specifically designed to produce environmental conditions to maximize plant growth.
Radiation Detectors
Radiation detectors are used for medical diagnoses, radioactive dating measurements, and measurements of background radiation, activity levels and radiation doses.
Refractometers
Refractometers measure the critical angle of refraction through a sample. The critical angle of refraction will change with concentration.
Solar Radiation Instruments
Solar radiation instruments measure the spectral range of radiation, including global solar radiation (sun + sky), net radiation (incoming solar - reflected solar) and the photosynthetic light spectrum.
Sound Level Meters and Noise Dosimeters
Sound level meters and noise dosimeters are used in sound and noise analysis. Applications include industrial safety, traffic noise studies, and scientific noise measurement.
Temperature Forcing Systems
Temperature forcing systems provide heating, cooling and/or a humidity and temperature controlled atmosphere to a separate test chamber, platform, or testing unit.
Temperature Indicators
Temperature indicators are designed for temperature monitoring and analysis. These devices either come equipped with an integral sensor, or require sensor input.
Thermal Imagers
Thermal imagers detect heat patterns in the infrared wavelength (1 micron to 100 micron) spectrum.
Thermal Platforms and Thermal Plates
Thermal Platforms provide heating and cooling with more precise temperature control for environmental or climatic testing.
Titration Instruments
Titration instruments are used to determine the concentration of dissolved substances. Titration is based on a complete chemical reaction between the specific substance, the analyte, and a reagent or titrant of known concentration that is added to the sample.
Total Organic Carbon (TOC) Analyzers
Total organic carbon (TOC) analyzers measure the amount of total organic carbon present in a liquid sample.
Turbidity Instruments
Turbidity instruments measure the average volume of light scattering over a defined angular range. Both particle size and concentration of suspended solids as well as dissolved solids can affect the reading.
Volatile Organic Compounds (VOC) Analyzers
Volatile organic compound (VOC) analyzers are used to detect concentrations of heavy hydrocarbons in gas or liquid media.
Water Quality Photometers and Colorimeters
Water quality photometers and colorimeters are ion-specific, computer-interfaced probes that are designed to determine the concentration of a solution from its color intensity.
Water Quality Testing Instruments
Water quality testing instruments are used to test water for chemical and biological agents, and to measure variables such as clarity and rate of movement.
