GSM GPRS 3G Power Meter & Power Transformer Monitoring Controller

A Professional & Biggest GSM SMS Controller, GSM GPRS 3G M2M, GSM GPRS 3G RTU Automation, GSM GPRS 3G Telemetry Data Logger

OEM ODM Manufacturer since 2005.

Name: GSM GPRS 3G Power Meter & Power Transformer Monitoring Controller

Model:S251

The GSM GPRS 3G Power Meter & Power Transformer Monitoring Controller is not only a smart power meter for measuring the power distributor voltage, current, factor, watts, frequency, active power, reactive power, when over current or exceed the pre-set value, will alarm immediately. but also can be used for monitoring the oil temperature, oil level of the transformers.

The GSM GPRS 3G Power Meter & Power Transformer Monitoring Controller was designed as a smart GSM/SMS/GPRS/3G power meter for measuring the power distributor voltage, current, factor, watts, frequency, active power, reactive power, when over current or exceed the pre-set value, will alarm and send SMS to users immediately.

The GSM GPRS 3G Power Meter & Power Transformer Monitoring Controller also can be used for monitoring the oil temperature, oil level of the transformers. when the oil temperature or level exceed preset value, will alarm and send SMS to users immediately.

Moreover, it can be used as a wireless transformer monitoring system for the transformers, e.g.: theft-proof, fall down, and so on.

1. How to make sure the quality?

Process Quality Control
Final Quality Control
Outgoing Quality Control

2. How to get the order?

First,Tell us the model and quantity of the products you want.
Second ,we will make a PI for you.
Third, After confirm everything,the payment will be arranged (Paypal, Western Union,T/T or Ali Trade Assurance for your money safety are welcomed)
Fourth, we will send you the goods within the promissory time.

3. How about the Shipping?

The DHL,UPS,Fedex,TNT usually calculate the shipment based on measure size or weight. They compare the measurement size in Cube meters and Gross weight, and choose the large value to calculate the shipment cost. (Calculation Formula is : L*W*H/5000=Measurement Size weight, unit is cm)

Reference Shipment Cost

For example, ship to Denmark from China.

Weight(Kg)	Shipment Cost	Average Cost for per Kg
0.5Kg	22.32USD
1Kg	28.27USD	28.27USD
16Kg	206.83USD	12.93USD
21Kg	147.13USD	7.00USD
31Kg	210.00USD	6.77USD
51Kg	316.00USD	6.20USD
101Kg	590.00USD	5.84USD
201Kg	1145.70USD	5.70USD

Our recommends:

For samples, ship by Express, usually 3-5days.

While place small order, try to make the finial weight more than 21Kg.
