Modifications

We've done a redesign of the internal electronics of the controller range to improve reliability.

• This includes a more precise Real Time Clock,
• a more precise air pressure sensor,
• improved board connections.

The alarm setting now enables to set 2 different times, one for each control. I.e. that the alarm setting can be enabled or disabled per channel.

Unfortunately have the models R3620 and R3624 lost the possibility to measure and control Dissolved Oxygen. It is however a great device to use and control Ion Selelective electrode measurements.

The model R3610SP is a special version of the model R3610 with pre-set parameters (can be adjusted!) for the control of pH and ORP (mV):

• CH1 → pH
  • Proportional Control
  • Hi = 7.35 pH controlling relay 1
  • Hys = 0.10 pH
  • dP = 0.50 pH
  • dt = 30 s
  • Pt = 30 s
• CH2 → mV (ORP)
  • Proportional Control
  • Lo = 650 mV controlling relay 2
  • Hys = 50 mV
  • dP = 100 mV
  • dt = 30 s
  • Pt = 30 s

This model has also an additional setting for the dependencies of the controls on each other. There are 3 possibilities:

• 2 is dependent on 1: i.e. CH2 won't be controlled if a control is active on CH1
• 1 is dependent on 2: i.e. CH1 won't be controlled if a control is active on CH2
• No dependencies, each channel is able to control its parameters independently of the other channel

The conductivity measurement has been disabled.

Our goal is to create kits (packages) which are most suitable according the instrument and use of that instrument. Since we have various customers in various domains this is not easy.

For C3000 and C6000 series we noticed that people generally prefer glass electrodes over epoxy electrodes. Certainly for EC measurements. So we decided to change the current kits and create new kits so that both options would still be available.

The new versions contain the following items:

You can see that the former P, K, PK and T kits are now renamed to PE, KE, PKE and TE.

We changed the specifications of our C3010 so that it has the same measurement capabilities as the C3020. The new C3010 can now also measure Dissolved Oxygen. This results in C3020 being obsolete.

C3020 will still be available at the same price of C3010 until the end of 2014.

As a results of this the T-kit of C3010 changes.

The NEW C3010T and C3010TE has a SZ10T added!

Besides a negative price correction in the whole R36xx series we also added the following to the R3610:

• Two programmable 4-20 mA recorder outputs.
• Two-way communication with any computer using RS485.
