Tunze Controllers for sale (Cond., Temp, PH)

[topsoil]

Next up for sale out are three older Tunze controllers.

Tunze Conductivity Meter 7032M - $30
(tried several times to calibrate the meter, but it is a couple of points off when trying to calibrate to the 50uS solution. talked to Roger at Tunze also, and there really isn't anything that can be done without tinkering with the circuit board. the 600uS calibrates fine.)

Tunze Temperature controller 7027/2 - $80
Works great. was using it to control my heaters with the switched socket.

Tunze PH controller 7070 - $100
No probe or calibration fluids, just the unit as seen in photo. 9V AC adapter was retrofitted into the unit, to keep from constantly changing out 9V batteries.

Tunze switched socket - $25
I only have 1 switched socket, which I was using with the temperature controller. All three meters can use the switched socket to control a device. The switch has european plugs, so I used an adapter. In the photo, it's the white box.

Will sell everything for $200. see tunze.com for info on controllers and accessories.

Located in NW San Antonio near Prue & Babcock. PM if interested.
Thanks!
