Process Grade

Process Grade sensors are wider and come equipped with 3/4″ or 1″ NPT mounting threads both on the sensor end and on the cable end for easy process mounting in either ‘submersible’ or ‘in-line’ configurations. They can be mounted either directly into a side wall or cover, to a PVC pipe and inserted at depth, or screwed into a pipe T junction.

Intro to I/O

Hot Tap Ready Lab Grade

Hot Tap mounting allows a sensor to be inserted and extracted from a live process without the need of lowering the liquid level. This means you can keep your process going without interruption while you calibrate or perform maintenance. Simply mount the ALS-HT1 Hot Tap to your vessel and insert the sensor.

Micro Manage Your Culture with Extra Control Modules

SPARC2 Boxes

All SPARC2 control boxes always include 2 high quality solid state relays, either AC or DC. This covers many scenarios.

 Relay Boxes

For more on/off devices, use our ALS-MER6 relay boxes, with 6 all-purpose relays.

 PWM Relay Boxes

For LED dimming, either use the ALS-SPARC2-D box, or for more relays add the ALS-SSR6 unit.

 Analog Outputs

Other lights and various devices require a 0-10 V input. Use the ALS-DAC4-10 unit for these applications.
