Portable Digital Earth Tester features three measurement ranges, data hold function and a large, easy to read backlit display.
The Sanwa PDR4000 is a digital Earth resistance tester designed for measurement within the CAT II 400V and CAT III 300V ratings.
This instrument is required for inspection and maintenance of electrical construction work. The PDR4000 has a safe design compliant with the IEC-61010 standards and is IP30 rated. This device has 3 measurement ranges, 40Ω, 400Ω, and 4000Ω, and can measure the Earth's resistance with an accuracy of 2%.
This device has a 4000 counts digital display with a backlight. It has a Data Hold function that allows users to hold or pause a measurement on the screen. It also features the Relative function that stores the existing reading (a delta) and resets the display to zero. 3-pole / 2-pole earth resistance measurement can also be performed with the PDR4000 but an optional accessory, TL-68 is required for 2-pole measurement.
The device is also capable of measuring interference voltage, but if interference voltage is greater than 10 Volts the Earth resistance measurement cannot be performed. DC elements of the interference voltage cannot be detected with this device.

$ 307.06 inc VAT$ 307.06 inc VAT Add to cartThe Sanwa PM7a is a pocket-size digital multimeter with a unique foldable design.
This digital multimeter has a 4000-count display and has an accuracy of 0.7%. The device has a unique design that features an integrated protective casing that allows it to fold just like a flip phone. The device is designed to be portable and to be used for measuring weak current circuits. A similar unit is also available with integrated solar power backup (Sanwa PS8a).
The PM7a can pretty much do all the basic functions such as measuring voltage both AC (500Volts max) & DC (500 Volts max), resistance (40 mega-ohms max), continuity test with buzzer as well as diode test. It cannot however measure current.
The PM7a has a power-saving design with an auto power off feature that turns on after 15 minutes of inactivity. It consumes approximately 5mW of power and requires 2 LR44 (1.5V) coin style battery to operate.

$ 51.03 inc VAT$ 51.03 inc VAT Add to cartThe Sanwa RD700 is a 4000 count digital multimeter with 0.3% accuracy.
The RD700 is designed for low voltage circuits, home appliance measurements, and small communications equipment. This device comes in two variants, the RD701, and the RD700. The only difference between the two is that the RD700 does not include the AC True RMS feature for measuring AC sine waves.
The RD700 comes with a 4000-count large format display and has an accuracy of 0.3%. It can be used to measure basic electrical parameters such as voltage, current, resistance, frequency, capacitance as well as temperature (300 ? max) using an optional K-type thermocouple sensor (K-250PC). The device features an ADP function for the current sensor, so that users can use the compatible current clamp sensor (CL-22AD & CL-22DC) to measure current in a conductor.
This device has an auto-power off mode that turns the device off after 30 minutes (cancellable). It also features an alarm for wrong probe insertion in the current terminal. The meter has a fuse of 20 kA and has a protective holster with a wall hanger/lead holder and a tilting stand.

$ 136.37 inc VAT$ 136.37 inc VAT Add to cartA convenient multimeter with it's own built-in, shock resistant case.
The YX360TRF is a taut-band type meter designed for low-voltage circuit measurements. It can measure DCV, DCA, AC, resistance, capacitance(10uF), Load line current, Signal power in dB as well as high DC voltage of up to 25kV using an HV-10T probe (optional). When measuring DCV the meter utilizes the Null reading for ±25V with an accuracy of ±5% full-scale accuracy.
This multimeter has a solid cover that provides protection against drop shocks, and conveniently folds over to use as a tilt stand, and features a compartment for storing the attached test leads. For circuit protection, the device features a replaceable fuse rated at (250V / 0.5A).
