Multiparameter Digital pH, ORP, Temperature Probe

SKU : 16a1c5ef4f16

The BL120 and BL121 use a multiparameter digital HI1036-1802 probe that incorporates pH, ORP, and temperature sensors along with a matching pin. All readings are measured within the probe and the data transferred to the controller by a digital connection. Both a digital connection and matching pin provide for stable, reliable measurements. Without these two components, electrical noise from recirculation pumps and ground loops can interfere, causing erratic readings and premature probe failure.

  • All readings are measured within the probe and the data transferred to the controller by a digital connection.
  • Digital connection and matching pin provide for stable, reliable measurements.
  • The HI1036-1802 with the BL120 or BL121 pool controller helps to promote the health and safety of pool and spa water.

Deskripsi

 

Potential matching pin

This probe also incorporates a potential matching pin. The matching pin is considered the “earth ground” connection and is used to prevent ground loop effects from causing erratic readings and damage to the system.

Specialized pH glass

The pH glass has been chosen to produce stable quick equilibration even in low conductivity waters. Additionally, the pH sensor is designed to produce a mV value near pH 4 (not pH 7 like typical pH sensors) should it stop working. A broken pH electrode that produces a mV value near pH 7 would produce an alarm state and disable any pump activated.

ORP

The ORP sensing surface is a large smooth surfaced platinum band that encircles the circumference of the temperature probe. It is referenced to Ag/AgCl reference electrode (3.5M KCl).

Differential measurement technique

The ORP and pH sensors and reference electrode use a differential measurement technique which is known to stay in service and provide accurate measurements under adverse conditions that may cause conventional pH probes to produce erroneous measurements. With the differential technique, a ground loop current will flow through the low impedance path of the matching pin thus providing immunity to the measurement signals

Digital signal

The probe converts these measurements to a digital signal to eliminate noise and static due to high impedance signals carried by cable

DIN Connector

Multi-pin sensor connector is manufacturer specific and allows for easy connection to the compatible meter.
