SG201RIT Reference, Glass, 12mm, Calomel Free, Refill by Sensorex

Calomel Free pH electrodes!

The performance of a Calomel electrode is now available without the hazardous Mercury associated with the design. The "Calomel Free" design features an Ag/AgCl based double junction reference with a unique silver ion trap acting as a third junction to impede any silver ion contact with the sample. Reference output is adjusted to deliver the same output as a Calomel electrode using a silver chloride reference.

Glass or Plastic Body Electrodes!

Traditionally, pH electrodes have been made of all glass construction. However, today's thermoplastics are able to construct pH electrodes with durable and chemically resistant bodies to reduce any breakage. The protected design of the plastic body electrode extends over the measuring surface, making the pH glass bulb virtually unbreakable.

Sealed vs. Refillable Reference!

Both sealed and refillable styles are available. Sealed references are gel-filled and maintenance free while refillable designs extend electrode life by having a refillable reference electrolyte.

Features:

• Fast Response...No Silver Ion Contamination
• Use in Place of Calomel pH and Reference Electrodes
• Combination Triple Junction Design
• Uses No Hazardous Calomel Based Material (MERCURYFREE!)/RoHS compliant
• Sealed and Refillable Models
• Glass and Epoxy Body Models

0563 8312 830-T2 IR Thermometer Kit with Surface Probe and Pouch with Belt Clip by Testo

The testo 830 is a universally applicable infrared thermometer for non-contact measurement of surface temperatures in trade and industry. Thanks to a new processor, and therefore better resolution, even more precise measurements are now possible. Temperature can now be recorded to an accuracy of 0.1 °C. Thanks to the min./max. function, the limit values of the last measurement can be displayed and even better monitored.

Kit includes:

• Infrared thermometer with protective leather case
• Cross-band surface probe (0602 0393)
• Batteries
• Factory calibration certificate

• 10:1 focus
• Backlit display
• Audible/visual alarm
• Emissivity adjustable from 0.2 to 1.0
• Fast readings
• Laser sighting
• Adjustable alarm limits
• Audible and visual alarm if limits are exceeded
• User-friendly thanks to "pistol design"
• Backlit display
• Adjustable emission factor (0.1 to 1.0)
