The OTT ADC (acoustic digital current meter) is an acoustic flow measuring instrument for the measurement of point velocities in open waters (eg, rivers, small streams, irrigation canals and so on). It calculates discharge measurements according to EN ISO 748 and USGS standards. It combines the plumb-line method with innovative technologies for the measurement of flow velocity and water depth. Approved acoustic measuring principles combined with a high-end signal processor provide precise and reliable data.
The Aqua Plus from Aquaread is an optical dissolved oxygen system that measures salinity directly.
The Eutech economy handheld range of meters is available in a number of parameters, including pH, ORP, conductivity, TDS, salinity and dissolved oxygen, and is suitable for basic water testing.
The HydroSense water content sensor system combines a compact, handheld display and a soil water sensing probe in a portable package to provide quick and reliable soil water content measurements.
The Vaisala CS106 barometer is claimed to provides accurate, reliable measurements of barometric pressure from 500 to 1100 mb (approximately sea level to 3658 m).
The CS547A conductivity sensor measures the electrical conductivity (EC), total dissolved solids and temperature of water and is suitable in most surface water, laboratory and industrial applications.
The HMP155A is an air temperature and relative humidity (RH) sensor that provides measurements for a wide range of applications and can be used as part of a weather station system or as a single instrument.
The 109-L temperature probe has been designed to operate with the CR200 range of data loggers. The probe accurately measures the temperature of air, water or soil in a range of applications.
The Campbell Scientific DMM600 duff moisture meter measures volumetric water content of organic forest floor material. It is a portable, battery-powered device that uses measurement methods sensitive to the dielectric properties of the material being measured.
Campbell Scientific has replaced the CR200 series data loggers with the CR200X series data loggers that feature expanded memory for the program and operating system (OS).
The bbe DaphTox II is a biomonitor, an enhanced version of the DaphTox, which gives early warning against a wide range of toxic concentrations.
The Series TE Duct and Immersion Temperature Sensor can be used to monitor air or water temperature throughout a building management system or an air handler unit. Flanged duct sensors monitor the supply or return air and provide a thermistor or RTD output to the digital controller. Immersion sensors, which are supplied with compression fittings, are typically used to monitor the hot or chilled water lines throughout a building. Thermowells are recommended, but not required, on the immersion sensors.
Holroyd High School is forty-one years old this year. The school buildings have the usual plumbing ‘issues’ you would expect in a school of this age, including pipes that may be in less than pristine condition.
The Panametrics DF-100E series of oxygen analysers includes the DF-130E, which is designed to provide reliable, dependable and accurate measurements at an economic price. Depending on the application, the sensor can operate for years without recalibration. The only maintenance requirement is the occasional addition of replenishment solution and an alarm is included. The device offers limited options from plumbing, analog outputs and miscellaneous features.
