The Combo series of combination waterproof
testers with advanced functions now includes the new model HI98121 for
simultaneous pH and ORP measurements. HI98121 also reads temperature, which is
continuously displayed on the dual level LCD. The pH electrode fiber junction
can be easily pulled out for replenishment. The pH electrode cartridge can be
quickly replaced with the supplied electrode removal tool. The encapsulated
external stainless steel temperature sensor provides a fast response due to its
close proximity to the pH electrode. The HI98121 works with common batteries
and displays the percentage of battery life remaining when turned on. The
stability indicator ensures reliable readings.

the HI73127 replacement probe.
The HI98121 is supplied complete with protective cap, electrode removal tool,
batteries and instructions.
For ORP calibration, we
suggest HI7022M, a 230ml bottle of 470mV solution, $19.
