SXL-DVX1 Drain System with Valve by Agrowtek

Electronic optical "liquid level control system" includes two liquid sensors for high and low "fill" or "drain" control of fluids in tanks, reservoirs, etc. Only power and a valve or relay is required to complete the level control system; no external controller required. Easy to wire and setup. Includes one standard and one latching sensor. Compatible with 5-24Vdc valves and relays. Available with optional VX1 water valve kit or RX1 outlet kit for direct operation of 120Vac pumps, valves and other equipment.

0590 7503 750-3 Voltage, Continuity, Phase Sequence Tester with GFCI Test, 3 Digit LCD, & Flashlight by Testo

The testo 750 voltage testers are the first instruments to include an all-around viewable LED voltage indication. All three models include low input impedance, phase sequence, continuity test, and meet CAT III 1000 V CAT IV 600 V safety standards.

The testo 750-2 includes a single probe voltage testing, built-in flashlight, and GFCI test function. The 750-2/-3 can perform GFCI Circuit tests on AC outlets. When performing a GFCI circuit test, a 35 mA load is applied to the circuit.

The testo 750 vibrates ensuring that the GFCI circuit test is active. In addition to the above features, the testo 750-3 includes a 3-digit LCD showing the actual voltage measurements.

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.

• GFCI Test Function
