98766-88 Traceable Relative Humidity Meter with Dew Point and Calibration by Digi-Sense

This pocket-sized thermohygrometer measures full-range relative humidity, temperature from -4 to 122°F (-20 to 50°C), and calculates dew point. Compact design features an electronic capacitance polymer film sensor - not affected by condensation.

Quickly recall minimum and maximum RH and temperature values, and freeze data readings with the press of a button. The dual-line display simultaneously shows humidity and either current or dew point temperature. Unit turns off automatically after 20 minutes of non-use to conserve battery life.

Traceable® Products have an individually-numbered Traceable® Certificate provided with each unit, that assures accuracy from our ISO/IEC 17025:2017(1750.01) calibration laboratory accredited by A2LA. It indicates traceability of measurements to the SI units through NIST or other recognized national measurement institutes (NMI) that are signatories to the CIPM Mutual Recognition Agreement. Each product goes through an intense vetting process before it can carry the Traceable name, thus saving you both time and money by not having to calibrate separately.

• Includes NIST-Traceable certificate from our A2LA accredited (1750.01) calibration laboratory
• Full-range response time less than 1 minute
• Sensor is not affected by condensation - measure up to 100% RH

Includes

Two AAA batteries, probe cover, and NIST-traceable calibration certificate with data.

LabSen 855 Pre-Pressurized Glass-body pH/Temp. Electrode for Highly Viscous Samples with Strong Alkali or High Temperature by Apera

Crafted with proprietary sensor technologies and premium materials from Switzerland, Apera LabSen 855 Glass pH/temp. Electrode is engineered for high-precision pH measurement of viscous liquids such as cosmetics, skin care products, paints, coatings, glues, slurry, honey, liquid resin, etc.

• The pre-pressurized electrolyte ensures a smooth electrolyte discharge for quick response, eliminating the common issue of junction clogs when testing viscous samples
• HA membrane for minimizing alkaline error and withstanding high temperature
• Silver Ion Trap reference system outperforms ordinary Ag/AgCl systems by maintaining reference potential stability over time with Ag+ free environment, which significantly extends the electrode's service life.
• Sturdy glass membrane, 10 times stronger than traditional glass membranes
• The built-in temperature sensor enables automatic temperature compensation.

CS150TC-K=0.1/10K/10/TL/TL Light-Duty Contacting Conductivity / TDS Sensor with Automatic Temperature Compensation (ATC), Graphite, 12mm, TC, K=0.1 by Sensorex

The CS150 and CS150TC conductivity probes are a cost effective solution for measuring conductivity in light industrial and laboratory applications.

Sensors feature measuring surfaces. The durable epoxy body construction provides a rugged and dependable sensor for portable and laboratory use. Suitable for use with most portable conductivity meters.

By adding a simple mounting gland fitting, customers may use these in process applications. Mount them in-line, in a pipe "T" fitting, or submerse them into a tank.

Features:

• Ideal for laboratory and light duty process applicationsAvailable with or without ATC (temperature sensor)
• Easy to submerge in a tank or mount inline in a pipe
• Cell constant choices of 0.1 or 1.0
• Compatible with most portable and benchtop meters
