WD-35641-51 Double-junction, Epoxy-body, Polymer Gel-filled pH Electrode (Use with all OAKTON pH meters except pH Wand and pH/CON 10) by Oakton

Use with any meter with a BNC connector

Choose a single junction electrode for field, clean water, and general purpose applications. Choose a double junction electrode for most applications, including dirty water, heavy metals and organics applications.

All electrodes have a BNC connector, and are 12 mm dia with a 3 ft cable (except submersible electrode, which is 25 mm dia with a 10 ft cable). We offer many other pH and ORP electrodes for specialty applications.

• Each 12 mm electrode includes a FREE electrode saver bottle to extend electrode life
• Use ORP electrodes with meters that read mV to take REDOX readings

WD-35625-16 Food TempTestr Mark-I IR Thermometer, with NIST Traceable Certificate of Calibration by Digi-Sense

Ensure your food is at the proper temperature without contamination worries!

Our TempTestr IR Food model is optimized for the food preparation industry. It offers ±1%/1°C (2°F) accuracy in the HACCP critical temperature range of 0 to 60°C (32 to 150°F). This tester s high spectral response lets you take readings through steam. Laser sighting lets you pinpoint your exact target.

• Offers high ±1°C accuracy at HACCP critical temperature ranges
• Infrared temperature measurement provides safe, noncontact readings
• Laser sighting pinpoints your exact target
• °F/°C selectable
• Simple one-handed operation just point and press button! Extremely rapid response time 1/2 second for 95% response

WD-35607-50 Conductivity/TDS Cell, Epoxy Body, K=1.0 (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)
