Used KH Director with probe and reference solution (not reagent).
I've had it working for the last two years on and off.
Readings have been pretty constant but you might want to pick a new probe when you order more reagents.
$500 for everything shipped
or
$325 for KH Director
$225 for the Slave Doser
