new exclusive PH-221 Controler "Special Edition Waterproof"
has a waterproof ph electrode with mini
BNC-connection (L: 10,5cm, D: 2,0cm). The device has a alarm
function for under- or exceeding a threshold value and a 2 point
auto buffer recognition. The controler is fully
supplied operationally and calibrated.
PH-221 is not only a very reliable, and highly exact pH measuring
instrument (0.02ph) with an 4-digits LCD display with blacklight,
it also works as controler for the regulation of the pH
value in liquids e.g. water in ponds, aquarium, swimming
pool, whirlpool, spa or pool etc.
simply set the desired pH value at the controller. If the currently
measured ph-value increases or decreases this deviation will be
adjusted by the PH-221. This is done with the relay-steered 230V
plug socket connected to to the controller, which is powered on
or off depending upon requirement. You can attach every 230V device
to it e.g. air outlet stone, oxygen pump, CO2-regulator,
electromagnetic valve... The PH-Electrode and Temparature
probe are included.

device and appplication please see our electrode
in connection with a CO2-dosing system (single
magnetic solenoid valve) or a CO² generator the pH value
in the aquarium can be controlled and being held at a optimal level
for the aquatic plants and fishes. The range of control enclosure
pH values from 3,5 to 10.5 and is digitally adjustable.
