Trident calibration fluid, Apex ORP probe, and Advanced sensor module (ASM))

[tankreefer]

I have some used equipment trying to get rid of. All prices are shipped.

Trident calibration fluid (sealed): $20 shipped

Apex ORP: used for 8 months, readings are accurate and consistent, stored in fluid: $ 70
Needed the extra port, only reason why I’m selling.

ASM: Box, aquabus and PAR sensor: $70
Plugged it in and got a reading on my apex
but cannot attest to the accuracy of the PAR number received. If nothing else you can use the box and aquabus to hook up other equipment.

I will take the ASM.

ASM sold!

ORP and calibration fluid remain.

Thanks so much for the ASM!
