WD-35607-53 Conductivity/TDS Cell, Glass Body, K=10 (Use with CON 100, 200, and 500 meters) by Oakton

Feature built-in temperature compensation

Each conductivity/TDS cell features a 3-ft cable and a two-band platinum sensor. Epoxy body cells have a temperature range of 0 to 80°C; glass and stainless steel body cells have a temperature range of 0 to 100°C.

• Epoxy, glass and stainless steel models available

Choose from three different cell constants.

• K = 1.0 for midrange conductivity measurements.
• K = 10.0 for high conductivity measurements (near or above 20 mS).
• K = 0.1 for low conductivity measurements (near or below 20 µS)

WD-35625-41 Economic 2-in-1 Food Safety IR Thermometer by Digi-Sense

A combination contact/noncontact thermometer for all food applications

Check critical food temperatures and monitor HACCP food safety zones with this combination contact/noncontact thermometer. LED s rapidly indicate if food temperature is in the bacterial growth safety zone. Green lights indicate safe temperatures below 40°F (4°C) and above 140°F (60°C). Red light indicates the HACCP danger zone between 40 to 140°F (4 to 60°C). The contact probe swings out for internal temperature checks, then folds in for storage. IR mode provides quick, noncontact surface measurements and stores maximum reading. Target illumination indicates target measurement area and is ideal for close working distances of 2 to 12 . Countdown timer with alarm monitors cooking and cooling intervals and HACCP exposure times set countdown timer to a maximum of 8 hours.

• Go/no-go LEDs provide quick check of HACCP food zones
• Sealed IP54 housing make for easy cleaning

WD-35614-79 pH 300 & pH 310 Meter Calibration Kit by Oakton

Calibration kit includes pH buffer pouches (five each of 4.01, 7.00, 10.00, and rinse water), squeeze bottle, and hard carrying case. (Meter not included)

WD-39643-00 Digi-Sense Palm-Sized Infrared Thermometer by Digi-Sense

Laser sighting and adjustable emissivity at an economical price

This infrared thermometer provides quick and accurate temperature measurements. View the current temperature, temperature scale (°F or °C), and battery life icon on the large LCD. Two battery compartments provide power to the thermometer and laser separately.

This gives the flexibility to measure temperature without the laser sighting if the laser battery is weak. Other features include selectable °F/°C, min/max measurements, lock function for continuous monitoring, automatic data hold, auto off, and battery life icon.

• Includes CR2032 batteries (2)
• Compact, ergonomic design provides a comfortable fit during use
• Fits perfectly in your hand or pocket
