2 settable SPST relays RS485 Conductivity /TDS Transmitter For Sewage water
DRFN conductivity instrument, strong environmental adaptability, clear display, simple operation and excellent test performance make it have a high cost performance.
It can be widely used in thermal power, chemical fertilizer, metallurgy, environmental protection, pharmaceutical, biochemical, food and tap water and other solutions for continuous monitoring of conductivity values.
The conductivity meter is equipped with an electrode with a constant of 1.0 or 10 to measure the conductivity of general liquids; with an electrode of 0.1 or 0.01, it can accurately measure the conductivity of pure water or ultrapure water, especially suitable for power plant boiler feed water and steam On-line continuous detection of conductivity of high-purity water such as condensed water,

FAQ
Q1. What are the special advantages of the pH instruments?
A: The instrument can not only compensate the temperature of the test sample by connecting the temperature sensor, but also self-check the working temperature of the instrument in real time. When the working temperature of the instrument changes, the instrument compensates the hardware change caused by the temperature drift. Make the test results more accurate, this is a patented technology.
Q2. Does the operation interface support customization?
Yes, our operation interface can be tailored to customers' needs.
Q3.Can our company's logo be added to your company's products?
Of course, we support OEM services for customers.
Q4.How long is the warranty period?
The company guarantees the instrument for one year (12 months) from the date of leaving the factory, and the consumables and wearing parts in the equipment are not covered by the warranty.
Q5. Does the conductivity controller have an ambient temperature alarm function?
Our EC controller has ambient temperature alarm function
Q6: What is your shipping method?
A: Small orders are delivered with DHL, FedEx, TNT, UPS , EMS. Large orders are recommended to ship by sea.
Q7: How long will you give me the reply?
A: We can support you 24Hours online service via email, skype, what’sapp, facebook etc within 1 hour.
