The CT-200 Socket Polarity and Earth Leakage Tester is used for testing the correct wiring status and safety of standard socket outlets. It is a modern and durable piece of professional test equipment and is built to last. It should be an essential item in any electricians tool bag, but also is so easy to use that anyone can use it to quickly and accurately test the safety of either a new installed mains socket, or check the safaty of an existing one. In addition this tester also has a unique soft touch button which when pressed will test that an RCD in the circuit trips within 300ms when a nominal 30mA earth fault current is applied. A further button also detects raised earth voltages above 50VAC, and will identify any dangerous installations in seconds and without any exposure to live mains voltage. Three bright bicolour (red and green) LED's and a buzzer provide a quick check indiaction, which show incorrect wiring, missing earth, live/neutral reverse, earth/live reverse, missing neutral, live faults and those errors detected by the two pushbutton tests. It potentially is a lifesaver in that it can be used by anyone to check that a live circuit is correctly protected by it's RCD and give the peace of mind of knowing that the current will be cut off in the event of a potential fault situation.

The Fieldpiece Dual-Temperature Accessory, model ATH4, measures two temperatures simultaneously using the included k-type, wrap tab beaded thermocouples. The technology inside the ATH4 provides superior temperature compensation in rapidly changing environments commonly found while performing field service. Use the ATH4 to find Delta T and just about any temperature split you want to measure. Displays T1, T2 and T1-T2 on your Fieldpiece meter, handle or data logger. It is included with the HVAC Guide® System Analyzer to get target superheat and for the Target Evaporator Exit Temperature test. Fieldpiece offers a wide variety of k-type thermocouples for various HVAC specific applications. Use pipe clamp T/Cs with the ATH4 to check for blocked filters. Use wet and dry bulb thermocouples to find target superheat. How Does it Work? Converts the voltages from two K-type thermocouples to display temperature on any digital multimeter with industry standard jacks. For 0.1º resolution, use a DMM that displays 0.1mVDC. The ATH4 converts the Fieldpiece stick series meter, DL3 data logger and EHDL1 electronic handle to a one-piece dual-input temperature meter. Use the optional Fieldpiece ADLS2 deluxe silicone test leads or the AHDL1 adapter handle with the ATH4 for use with DMMs with industry standard jacks. Operation Insure the temperature being measured is stable. Maintain good contact between the thermocouple and what's being measured. Set the meter on 200mV or 2000mV range for 0.1º or 1º resolution respectively. Slide the switch to "T1" to measure display T1, to "T2" to display T2, and to "T1-T2" to measure the difference between T1 and T2. Velcro Tie-wrap Instructions Two Velcro straps have been included with the ATH4 to make it easier to measure pipe temperatures. Use the Velcro strap to hold the bead of the model ATB1 thermocouple against the pipe. Features: Designed for HVAC/R, the Dual-Temperature Accessory, model ATH4, measures two temperatures and calculatesthe difference in English or metric units. Field calibration for ±1ºF accuracy. Displays ºF directly at 0.1ºF resolution on DMM with 0.1mVDC resolution. Select ºF or ºC. Converts from -50ºF to 1800ºF (optional thermocouple required for 1800ºF) Includes two “wrap tab” thermocouples plus velcro straps. Thermocouples insulated to 400ºF. Auto-off can be disabled for data logging.
