0590 7701 770-1 TRMS Clamp Meter by Testo

The testo 770 Hook-clamp Digital Multimeter (DMM) is ideally suited for electrical work in HVAC applications. Testo's unique hooking clamp can be used to separate then grab wires. The easy hook-off retractable post releases the wires when testing is complete. You can safely work in tight spaces without using your hands. The 770 series identifies the testing in-process and automatically selects the correct meter configuration which saves you time and increases your accuracy.

The 770 series of instruments are rich in the features HVAC techs need and want including TRMS, starting current, and frequency measurement. The 770-2, which includes A can also measure temperature using the included Type K thermocouple adapter. The 770-3 (temperature adapter optional) additionally includes real-time power measurements (Watts), and Bluetooth. The 770-3 links to the Testo Smart Probes App and can be used for remote viewing, monitoring trending over time, and creating reports. The powerful app allows you to create custom reports that include photos, data, and graphs that can be saved or sent via email.

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.

18004-15 Traceable ONE Single-Use USB Temperature Data Logger, 10 Day, 1 Minute Interval, 2 to 8°C; 10/pk by Digi-Sense

These data loggers can be used for monitoring and recording temperatures during shipments, storage, or experiments. They are ideal for food, pharmaceutical, or laboratory use any application where a small accurate datalogger is required.

The data logger features a time delay of 30 minutes so the logger will not alert when the temperature is within the alarm zone, until the delay time elapses. Protective plastic pouch keeps logger dry, eliminating concerns when shipping materials with cold packs, ice, or in damp environments. To maintain IP67 waterproof rating, do not tear open pouch before data download.

Products have an individually-numbered 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.

• LED alarm indicator for visual status indication
• Time delay of 30 minutes before logging begins for enhanced logging accuracy
• Protective plastic pouch maintains waterproof IP67 rating
• Bar code for in-house scanning
• Includes NIST-Traceable certificate from our A2LA accredited (1750.01) calibration laboratory
• Compact, single-use datalogger with 10 day logging duration in 1 minute intervals
• Low to High alarm parameter range of 2 to 8°C

Includes

Battery (3.0 V CR2450 lithium) and NIST-Traceable calibration certificate with data.

AgrowDose™ AD1 Peristaltic Dosing Pump by Agrowtek

AgrowDose AD1 dosing pump is a rugged and economical singlehead peristaltic pump designed for injecting nutrient solutions, pH buffers and more into stock tanks or pressurized water lines up to 20psi.

AD1 Pump operates at a fixed speed (~50mL/min) when powered and requires a controlled outlet to operate the pump (such as RX1 or RX4.) Includes a standard wall plug power supply.

Pump heads feature an intlet tube and an outlet tube. Simply place the inlet side into any size nutrient or buffer stock tank and route the outlet to the reservoir. Pumps can draw solutions up to 10ft vertical lift and do not require priming. Peristaltic action resists fouling or clogging even with thick fluids.

Features

• Single dosing pump
• Precision dosing accuracy: Fixed flow rate, non-reversable
• Easy-change pump heads: Twist & replace; no tools required
• Durable powder-coated steel enclosure
• Made in USA
• 1-Year Warranty

Typical Applications

• Agricultural Nutrient or pH Dosing
• Industrial Chemical Dispensing
• Laboratory Dispensing
• Aquarium
• Pool & Spa
• OEM & Custom Applications
