A multipurpose electromedical safety tester has been upgraded to include new features and increase test routine efficiency. The 277 Plus tester from Rigel Medical (Peterlee, Durham, UK; www.rigelmedical.com) can be used for the safety testing of all electrical laboratory equipment. Additional test functions include touch leakage, voltage measurement, and a dedicated IEC 61010 measuring device. Manual, automatic, and semiautomatic test routines can be conducted, allowing full control of power up and power down delay times. The unit features a full graphics display, large internal memory, and integral qwerty keyboard.
A lightweight valve is designed to dispense low- to medium-viscosity fluids. The DV509 diaphragm valve from I&J Fisnar Inc. (Fair Lawn, NJ; www.ijfisnar.com) keeps wet parts separated from the operating air supply. Substances such as cyanoacrylates, reagents, UV adhesives can be dispensed using the valve. The 3-oz valve is capable of 200 c/min. Valves with stainless-steel and UHMW bodies are also available.

A family of rugged, low-cost dc/dc converters has been introduced. The JTA series of wide-input, 10-, 15-, and 20-W converters from XpiQ (Holliston, MA; www.xpiq.com) are a redesign of industry-standard models. The converters feature an extended operating temperature range of –40° to 100° C with full load available at up to 70° C. Ultrawide input voltages of 9–36 V dc or 18–75 V dc, and single or dual outputs in the 3.3 V dc to 15 V dc range are available. The 15- and 20-W converters include remote on-off and a 10% voltage trim facility. All units have integral over-voltage and over-current protection. The converters have 1500 V dc input-to-output isolation with an isolation resistance of 1000 MΩ.
