$100 - $150, Oakton Instruments

WD-35805-14 Platinum Band Sensor, Submersible, Single-junction, Epoxy-body, Gel-filled ORP 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-35811-71 Single-junction, Epoxy-body, Gel-filled pH Electrode (Use with pH 5, pH 6, pH 510, Ion 510, pH 1100, pH 2100 meters) by Oakton

Built-in temperature sensor lets you take ATC readings with a single probe

Each All-in-One Acorn electrode features a built-in temperature sensor for taking readings with Automatic Temperature Compensation (ATC). 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.

Each electrode is 12 mm dia with a 3 ft cable.

• Includes a FREE electrode saver bottle to extend electrode life
• Feature a BNC connector for pH and a phono jack connector for temperature

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
