0590 7602 760-2 Digital Multimeter with TRMS, Capacitance, LPF, Auto Setup, Duty Cycle & Temperature by Testo

Testo's exclusive auto-test setup enables the user to simply turn on the unit, connect the leads, and begin measuring. The testo 760 Digital Multimeter detects the lead connection and prevents switching from V to A or A to V if leads are not in proper socket. This prevents accidentally blowing the meter's fuse because of incorrect connections. The function and range settings are always correct because the measurement parameters are detected and set automatically. Three easy-to-read buttons replace the traditional rotary switch when selecting manual test functions.

Additional benefits:

• APO (Auto Power Off) saves battery life
• Overmold housing makes it rugged
• Large, backlit, dual readout display with analog bar graph is easy-to-read
• Lead holder conveniently molded into housing for easy storing

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.

• Auto test-setup based upon lead connection prevents blown fuses in the meter
• Meter prevents switching from V to A or A to V if leads are not in the proper socket
• Meter automatically detects testing in-process and selects correct meter configuration to save time and optimize accuracy
• 3 buttons that illuminate for easy and clear selection of test functions
• Low Pass Filter and Duty Cycle standard
• Measure up to 400 A with optional clamp probe adapter
• Heavy Duty - Drop and water resistant for tough conditions

BW Clip 2 Year Single Gas Detector, Hydrogen Sulfide (H2S), Low - 10 ppm / High - 15 ppm, Black Housing by BW Technologies

The BW Clip single-gas detector is your everyday companion for hazardous environments. It operates up to three years maintenance-free: Just turn on the device and it runs continuously - no need for calibration, sensor replacement, battery replacement or battery charging. That means great reliability and no downtime.

Plus, with the two-year BW Clip for H2S or CO, you can put the device in a hibernation case when you re not using it for a week or more - and extend its life by that period of time.

Compatible with both the MicroDock II and the IntelliDoX instrument management systems, the BW Clip is engineered to the highest standards of quality and reliability, keeping you safe and compliant.

Use our unique advanced technology for safety, compliance and productivity.

Surecell™: unique dual reservoir sensor design dramatically improves instrument performance, response time, and longevity compared to traditional electrochemical sensors and consistently delivers reliable instrument performance under the harshest environmental conditions

Reflex Technology™: advanced automated self-test function routinely checks the operating condition of the sensor to increase safety, up-time, and overall worker confidence

IntelliDoX: instrument management system

• The quickest bump test in the industry
• Confi guration of alarm set points and more
• Performing different tests for up to five BW Clip detectors at once - for maximum productivity

AI3104 LabSen 241-3 Glass-body pH Electrode for Micro Samples (>30 microliters) by Apera

Backed by proprietary Swiss sensor technology and premium materials, LabSen 241-3 Glass Micro pH Electrode is designed for micro-volume samples (≥30 microliters), especially suitable for microplates, microcentrifuge, and microbiological samples. With the ultra-micro container (sold separately), it can test as low as 15 microliters.

Unique Glass Membrane - LabSen 241-3 pH electrode adopts a micro cylindrical sensor tip (top end ø3mm, stainless steel ø4mm), making micro-sample pH testing easier than ever, and can be tested in high-temperature samples (up to 212°F). The stainless steel protective shaft ø4mm) ensures the durability of the slim glass tube.

Long-Life Reference System - composed of a glass tube, AgCl, and a reference silver wire. The top end of the slim glass tube is stuffed with cotton, which prevents the reaction between AgCl and electrolyte when the temperature changes. It improves the stability of the reference system and extends the electrode's service life.

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 Instruments MP500) to enable ATC or manually input temperature to achieve temperature compensation.

• Proprietary pH sensor technology and premium materials from Switzerland
• Low-resistance LabSen® micro cylindrical glass membrane, suitable for micro-volume pH measurement (>30 microliters)
• The stainless steel protective shaft ensures the durability of the slim glass tube
• Long-Life Reference System, improving the stability of the reference and extends the electrode's service life
• With the micro container (sold separately), it can test as low as 15 microliters.
