CP Voltmeter

We are proud to manufacture and export CP Voltmeter w/ Extension Stick, which is highly useful for cathodic protection survey. Digital voltmeter is an extremely rugged new instrument for measuring the DC structure to earth potentials of various buried or submerged metal structures. Using this instrument, the users need not to bend down or attach many connections. By this product, errors in measurement are reduced drastically because of specially made voltmeter for CP Survey.

Powered by 9 Volt Battery, it requires no push to read switch. The solid-state integrated circuit has built-in filter to reject AC interference. Input resistance of 10 mega ohms (10 million ohms) of this instrument results in potentiometer quality voltage readings. The instrument measures direct reading in mV when connected with half-cell.

Specifications:

• Range: 0-5000 mV DC

• Resolution: 1 mV

• Accuracy: +2%

• Sensitivity: 2 Volts

Features:

• Housed in 3/4" (19.05mm) thick PVC pipe.
• 9 Volt battery; long life expectancy
• Built-in battery tester
• Digital display on panel.
• No switch necessary to take readings
• Integrated circuit design
• Easy to plug half cell for measurements

Our range of Cathodic Protection (CP) Voltmeter is a revolutionary instrument for measuring DC structure-to-earth potentials of various buried or submerged metallic objects. Powered by an ordinary 9-volt battery, the Model CPV-4 gives an immediate reading in large ½ inch (12.7mm.) liquid crystal display numerals. 

The large scale integrated circuit has a built-in filter to reject AC interference. Input resistance of 11 mega ohms (11 million ohms) yields potentiometer quality voltage readings. The digital readout eliminates interpolation of voltages. This small, lightweight instrument requires no warm-up time. Being insensitive to the temperature, it can be read in direct sunlight. Low current CMOS circuitry assures long battery life and the die-cast metal case makes the CPV- 4 a durable instrument for the field.

Specifications:

Our range of CP Voltmeter CPV-2 T&R-USA is an extremely rugged new instrument for measuring the DC structure to earth potentials of various buried or submerged metal structures. Powered by two "AA" penlight cells, the Model CPV-2 requires no push to read switch. The solid state integrated circuit has built-in filter to reject AC interference. Input resistance of 10 mega ohms (10 million ohms) of this instrument results in potentiometer quality voltage readings. Red-is-bad and green-is-good segments with 0.85 V as the division line.

This versatile meter may also be used without the reference electrode to measure direct current potentials from 0 to 2 volts, such as potentials across an insulated flange, anode to structure, or structure to structure. The features and specifications hold the importance of CPV-2 T&R.
