ISO-TECH DIGITAL ILLUMINANCE METER


The ISO-TECH 1332A Digital illuminance meter is a precision instrument used to measure illuminance in the field. †It is fully cosine corrected for the angular incidence of light. The illuminance meter is compact, robust and easy to use. The light sensitive device used in the instrument is a very stable, long life silicon diode

Hanna Combo pH/EC/TDS/Temperature Tester With Low Range EC (Model HI 98129)

The HI 98129 Combo waterproof tester offer high accuracy pH, EC/TDS and temperature measurements in a single tester! No more switching between meters for your routine measurements. The waterproof Combo (it even floats) has a large easy-to-read, dual-level LCD and automatic shut-off. pH and EC/TDS readings are automatically compensated for the effects of temperature (ATC). This technologically advanced tester has a replaceable pH electrode cartridge with an extendable cloth junction as well as an EC/TDS graphite electrode that resists contamination by salts and other substances. This gives these meters a greatly extended life. Your tester no longer needs to be thrown away when the pH sensor is exhausted.

The EC/TDS conversion factor is user selectable as is the temperature compensation coefficient (Ŗ). Fast, efficient, accurate and portable, the Combo pH, EC/TDS and temperature tester brings you all the features you've asked for and more!

DiSTģ4 EC Tester

DiSTís are rugged and reliable pocket-sized testers that offer quick and accurate readings of conductivity or TDS. The DiSTģ family of testers is widely used for monitoring EC/TDS in drinking water, water conditioning, reverse osmosis, cooling towers, wastewater, laboratories, agriculture, aquaculture and aquariums, hydroponics and the printing industry.This tester features an amperometric graphite electrode that provides better repeatability in measurements since they do not oxidize. An amperometric measurement of EC is based on Ohmís Law, I = V/R where R depends on the distance between two pins and their surface. Oxidation changes both the distance and surface which will affect accuracy. The DiSTís non-oxidizing graphite pins are able to provide an optimal surface for accurate, dependable results.When calibration is necessary, simply submerge the electrode tip into calibration solution and adjust the trimmer on the side of the tester.

HYGROMETER


The Whirling Pattern Psychrometer offers the maximum level of accuracy due to the nature of measurement. Housed in a robust yellow plastic frame with black folding handle the instrument incorporates a water cistern linked to the 'Wet' bulb by means of the cotton sleeve. For your additional safety the thermometers' tubes are spirit filled.

  • Frame size: 230mm x 50mm
  • Range: -5o -+50oC
