proCHEM-pH Controller, 240V AC In, Dual Limits, 4-20mA Out
Choose between options: No Sensors, 5m Dip Sensors, or 5m Screw-in Sensors. 

PLEASE NOTE: This item is custom made-to-order and has a lead time of up to 9 weeks. Please contact us for an accurate lead time.

Dual Set Points. The default setup for these are as "Too High" and "Too Low" control points. The user can also re-set them so that they are both "Too High" or both "Too Low" control points. An example of this type of setup is where the proCHEM unit has one point set to control the process, and a second point beyond that set to activate an alarm.

Separate LED's indicate when either of the Set Points has been exceeded. The output relays are rated to 240V and are fused at 1 Amps. Higher currents can be switched with an external contactor.

All proCHEM units are easy to install. They are housed in a rugged plastic case which is non corrosive, waterproof and dustproof to IP65. All controls can be accessed via the hinged, clear cover. The large LCD display is easy to read, even from a distance.

The proCHEM series is designed for maximum flexibility. 4 to 20 mA and 0 to 1 V DC outputs are provided as standard.

Two different sensor options are available - choose between 5 metre dip or 5 metre screw-in pH & ATC sensors.

For a total solution to your control requirements, TPS also offers a peristaltic pump, the easyFLOW-VS.

The 
proCHEM series is proudly designed and manufactured in Australia. The TPS Quality System has been certified in accordance with AS/NZS ISO9001 standards. Since 1968, TPS has built a reputation for excellent backup service that is second to none.

Gentle, soothing, and perfect for sensitive skin
Scent: Unscented, Size: 3.4 Fl Oz (Pack of 1)
I’ve been using the Bioderma Sensibio Foaming Gel for sensitive skin for a few weeks, and it has quickly become one of my favourite cleansers. Despite having combination skin that’s prone to redness and sensitivity, this gel never dries me out or causes irritation. The texture is a clear gel that transforms into a light, airy foam — so gentle and refreshing. It rinses off completely without leaving any tightness or residue . What I love most about it: • foams lightly yet cleans thoroughly — removes dirt, oil and even light makeup without stripping the skin ; • unscented, soap-free, non-comedogenic, and pH‑balanced, so it respects my skin’s natural barrier ; • leaves skin feeling hydrated, soft and calm, not tight or dry . In my routine, I use this gel morning and evening. It’s perfect for days when my skin is more reactive — calming without being stripping. Even after wearing light sunscreen or daily foundation, my face feels fresh and balanced post-wash. ✅ Gentle enough for daily use ✅ Keeps skin barrier intact ✅ Effective at cleansing without irritation This cleanser is now a permanent part of my skincare lineup. I definitely plan to repurchase — ideal for anyone seeking a reliable, ultra‑gentle everyday cleanser.

Gentle, Refreshing, and Perfect for Sensitive Skin!
Scent: Unscented, Size: 500ml / 16.7 Fl Oz, Scent: Unscented, Size: 500ml / 16.7 Fl Oz
I absolutely love the Bioderma Sensibio Foaming Gel! I have very sensitive skin, and most cleansers either dry it out or leave a tight feeling afterward — but not this one. It has a smooth, silky texture that turns into a soft foam and removes makeup easily without any irritation. My skin feels clean, fresh, and hydrated after every use. I really like that it’s unscented, which makes it perfect for sensitive or allergy-prone skin. Even around my eyes it feels gentle and doesn’t sting at all. I’ve been using it morning and night for a couple of weeks, and I already notice that my skin looks calmer, less red, and very soft to the touch. A small amount goes a long way, so the bottle lasts a while too. Overall, this is one of the best cleansers I’ve ever used — gentle yet effective, and ideal for anyone with sensitive skin. Definitely deserves 5 stars!
