OCPF81-LH21E21 – pH Sensor with 3/4” MNPT Housing for Flow and Immersion

OCPF81-LH21E21, pH sensor with 3/4” MNPT housing for flow and immersion installations, 15’ cable and BNC. Patent Number 4,128,468 Bukamier, Patent Number 4,333,812 Bukamier, Rupert
 
Key Features
	
Porous Teflon junction delivers high performance and low maintenance
	
Double chamber reference system prevents fouling in harsh industrial conditions
	
Durable 0-14 pH sensitive glass can withstand CIP treatment and operating temperatures up  to 110°C, 230°F
	
Self-cleaning flat surface pH membrane option (see OCPF81-LH11E21)
 
Internal Plunger
	
This feature was patented by Innovative Sensors in 1982 and is available on most industrial sensors
	
Competitor’s sensors require mounting 15 degrees off horizontal. The expansion air bubble that exists in the pH sensing internal can migrate to the tip of the sensor and cause an  internal disconnect
	
Internal plunger allows for expansion of the liquid without the need for an air bubble
	
Enables mounting in any configuration (360 degrees)
