1-Phase/Single-Speed Motor, 1/3 Hp, 115/230V, 60 Hz, 1725 rpm

0590 7551 755-1 Current/Voltage Tester by Testo

The testo 755 current/voltage testers are fast and easy to use, especially when you are testing many circuits. The convenient open-jaw current tester automatically turns on when voltage exceeds 6V. It then auto-selects the correct parameters and range for your test. These rugged testers are suitable for virtually all your daily electrical measuring tasks. The instruments include important functions such as current, voltage, resistance & continuity. The integrated flashlight enables users to work in poorly lit areas.

The overall design is for convenient testing including interchangable measuring tips which can be easily updated and maintained. A convenient lead holder is integrated into the housing for safe and easy storage. The testo 755-2 includes important additional features: phase rotation, voltage range up to 1000V, and the unique feature which allows the user to check for voltage using only a single lead.

Testo's history of efficiency, innovation, and quality now extends into the entire electrical lineup. Once again, Testo brings high value, feature-packed products to the HVAC contractor market.

• Meter automatically detects testing in-process and selects correct meter configuration which saves time and optimizes accuracy
• Polarity detection for DC circuits
• 3-phase sequence check with motor rotation indication
• Single lead voltage test with audible indication
• Interchangeable measuring tips
• Built-in flashlight illuminates your measurements
• APO (Automatic Power Off) below 6 VAC

AI3168 LabSen 851-H Pre-Pressurized Glass-body pH Electrode for Highly Viscous Samples with Strong Alkali or High Temperature by Apera

LabSen 851-H pH electrode is designed for high-accuracy pH measurement of highly viscous samples with strong base or high temperature.

The pre-pressurized structure allows the electrolyte to stably flow out even in highly viscous samples so as to ensure reliable measurements.

HA Glass Membrane - better accuracy and repeatability in strong alkaline solutions (10 to 14 pH), minimizing alkaline errors.

The electrode uses a BNC connector, compatible with any pH meters that use BNC connectors. No temperature sensor is built-in. Users need to have a separate temperature probe (ex: Apera MP500) to enable ATC or manually input temperature to realize temperature compensation.

• PHY glass membrane made for high-temp. and caustic solutions
• Proprietary sensor technology and premium materials from Switzerland
• LabSen HA-type glass membrane designed for strong alkalis (pH 10-14), minimizing alkaline errors
• Pre-pressurized reference system for smooth electrolyte flow
• Silver Ion Trap Reference System ensures a stable reference potential and long service life.
• Lead-free glass body

GL100 Bacteria Tests: Hygenia SpotCheck Plus Rapid Glucose/Lactose Test, 100 pk by AquaPhoenix

SpotCheck Plus detects the presence of glucose and lactose on a surface. Simply swab a surface, release the reagent and if any residue containing glucose and/or lactose is present the reagent will turn green, indicating poor surface hygiene. The more contamination present, the quicker the color change and darker the color. SpotCheck Plus instantly validates the hygiene of a surface, allowing immediate corrective action to be taken if necessary.

WD-05993-70 Cole-Parmer® In-Line pH Probe, SJ/PVDF/100Ohm RTD/10'; Plug/BNC by Oakton

In-line electrodes operate from 32 to 212°F (0 to 100°C) and have a chemical-resistant PVDF housing with a 1/2" NPT(M) thread. Housing measures 4" x 15/16" diameter. Electrode extends 1" beyond housing. Maximum pressure 100 psi. Measure pH from 0 to 13.

93831-87 PFA-Ctd RTD Probe, 100 Ohm, ANSI 3-Blade Connector, 10" L, 5ft Coil Cord by Digi-Sense

Maximum error for probe assembly is ±1.1°C + 0.12% of reading below 300°F, ±0.35% of reading above 300°F. Alpha coefficient is 0.003850 Ω/Ω/°C (DIN IEC 751). Resistance at ice point (0°C) is 100 Ω.

Note: Time constant is the time required to reach 63.2% of the new reading. To determine how long it will take to reach 99% of the new reading multiply the time constant by five.

Note: The temperature range is for the probe tip only. The handle material may be affected if the probe is rated higher than the handle depending on exposure time, application, and handle material. ABS handles are rated to 220°F (104°C); PVC handles are rated to 200°F (93°C); Stainless Steel handles are rated at 450°F (232°C); Mini Connectors are rated to 392°F (200°C).
