Dual Channel PH/ORP Controller

APX2SeriesFeatures

 Connected to 2 pH or 2 ORP sensors, or 1 pH and 1 ORP sensor;

 Two Channels are isolated from each other

 Each channel can be connected to an independent temp. system.  When pH, ORP and temp. are tested at the same time, algorithm inside

the meter can simultaneously evaluate the disinfection ability and

display pH, ORP, temp. and chlorine values.  Meet pH/ORP monitoring, dosing control, and data signal remote

transmission at the same time.  Application: swimming pools, water parks, water treatment and dosing, ultrafiltration, circulating water, and other occasions. Specification

OLTUseriesDigital Laser Turbidity Sensor

Specification

The flow turbidity sensor shoots the 660nm laser vertically downwards into

the water. The light is scattered by suspended particles in the water sample, and the scattered light at 90°with the incident angle is received by the

silicon photocell receiver immersed in the water sample, and 90 °is

calculated.  Compact miniaturized design, small installation space

 660nm laser light source with high resolution and fast response

 Optional viewing window and automatic emptying system reduce

maintenance effort

 Low injection flow requirements, reducing the amount of waste

generated in the measurement

 Internal storage of calibration data, support offline calibration, on-site

plug and play
