TriMetric 12 - 48 volts    Battery Fuel Gauge

A quick look and you will know how much power is left in your battery. This meter can help you operate your energy system more effectively for better battery life and power. It shows and keeps track of amps going in or out of battery. Charge light shows when battery is charging. Battery reminder light shows when: 1. Battery should be recharged. 2. Battery needs equalize charge. 3. Battery voltage is too low. Extra memory features shows total days since full charge, amp hours removed since full charge, total amp hours removed from beginning— up to one million, maximum and minimum battery voltage since last reset. .Helps save valuable energy by letting you see how much you're using. Use "amps" reading to educate users about how much energy different electrical loads draw. Check that all loads are really off when you think they're off. Check for "phantom loads" small loads that steal power 24 hours per day. Keep informed about how much energy you have left in your battery system. Reduce generator use by knowing when you can efficiently shut it off because batteries are approaching full charge. Meter can be mounted almost anywhere it is convenient to read—even several hundred feet from the shunt which you locate at battery’s negative lead. 1 year warranty by factory. 4½”x 4¾”, 500 amp 50 mv shunt included. A 100 amp shunt is available for systems with smaller amp loads. Accuracy is the same with either shunt, but the 100 amp shunt allows an extra digit of amp resolution. Systems with inverters usually need the 500 amp shunt. We recommend the Lightning Protector to greatly reduce risk of lightning damage. TriMetric meter warranty is extended to cover lightning damage.

Kill A Watt meter      Electricity usage monitor

Kilowatt-Hours, Watts, Volts, Amps, Hz, Power Factor, Volt-Amps, Hours

The cost of electricity can really hit your where it hurts. Now with Kill A Watt you can reduce energy costs and identify the real energy abuser's. Simply plug your appliances into Kill A Watt and it will assess how efficient they really are. Large LCD display will count consumption by the kilowatt-hour just like your local utility company. You can figure out your electrical expenses by the day, week, month, or year. Evaluate the quality of the electrical power provided by your utility company by monitoring voltage (Volt), line frequency (Hz) and power factor (VA). Perfect for detecting voltage drops and brownout conditions before they damage delicate equipment. Find parasitic loads and wasted energy. Monitor refrigerator, freezer, microwave oven, toaster, mixer, clocks, TV, VCR, radio, stereo, lights, fans, garage door opener, computer, monitor, printer, copier, cordless phone, battery charger, clothes washer, gas clothes dryer, vacuum cleaner, etc. The knowledge you gain from Kill A Watt can save you thousands of dollars. Maximum voltage is 125 VAC, maximum current is 15 amps, maximum power is 1875 VA, 0.01 to 9999 KWH maximum, 9999 hours maximum. Counters will reset to zero when they reach maximum. 5-1/8" x 1-5/8" x 2-3/8". Limited warranty 6 months by manufacturer. Made in China.
