PH450G 4-Wire pH/ORP Analyzer

Truly unique is the EXAxt450 series in the Human Machine Interface (HMI). The high resolution graphical display and the touchscreen operation make all information visible to the operator. Configuration with the touchscreen is as easy as operating a PDA. Simply choose the language of choice and on screen instructions assure that the best configuration for the application is obtained.
The PH450 offers the best accuracy in the industry by combining the pH measurement with advanced temperature compensation functionality, preloaded calibration standards and stability checks.
The PH450 is a true multivariable analyzer that combines pH with temperature and ORP (Redox) measurement and all these measurements can be utilized through the different output functions: two mA current outputs, four independent SPDT contact outputs and HART®.

Features

*	Easy touchscreen operation.
*	IP66/NEMA4X 1/2DIN enclosure for field mounting and panel mounting.
*	Unique HMI menu structure in 8 languages.
*	Predefined buffer solutions.
*	Trending display up to 2 weeks.
*	On-screen logbooks store calibration data, configuration changes and events.
*	Advanced Process Temperature Compensation.
*	Three sets of preloaded pH buffer standards.
*	HART® Communications.
*	FM Class I, Div. 2, Group A, B, C and D, T6 for Ta -20 to 55℃.

Specifications

Measuring principle	Glass electrode method
Input ranges	pH: -2 to 16 pH ORP: -1500 to 1500 mV rH: 0 to 100 rH Temperature: -30 to 140 deg C (Pt1000)
Transmission signals	General: Two isolated outputs of 4 to 20 mA DC with common negative. Maximum load 600 Ω. Bi-directional HART® digital communication, superimposed on mA1 (4 to 20 mA) signal. Output function: Linear or Non-linear (21-step table) output for pH, temperature, ORP or rH. Control function: PID control. Burn out function: Burn up (21.0 mA) or burn down (3.6 mA) to signal failure accorded with NAMUR NE43. Hold: The mA-outputs are frozen to the last/fixed value during calibration/commissioning.
Contact outputs	General: Four SPDT relay contacts with display indicators. Switch capacity: Maximum values 100 VA, 250 V AC, 5 A Maximum values 50 W, 250 V DC, 5 A Status: High/Low process alarms, selected from pH, ORP, rH and temperature. Configurable delay time and hysteresis. Failure annunciation. Control function: On/Off, PID duty cycle or pulsed frequency control. Wash: Contact can be used to start manual- or interval time wash cycles. Hold: Contact can be used to signal the Hold situation. Fail: Contact S4 is programmed as fail-safe contact.
Contact input	Remote wash cycle start.
Temperature compensation Function	Automatic or manual. Compensation to Nernst equation. Process compensation by configurable temperature coefficient, NEN6411 for water or strong acids/bases or programmable matrix.
Calibration	Semi-automatic 1 or 2 point calibration using pre-configured NIST, US, DIN buffer tables 4, 7 & 9, or with user defined buffer tables, with automatic stability check. Manual adjustment to grab sample.
Display	Graphical Quarter VGA (320 x 240 pixels) LCD with LED backlight and touch screen.
Housing	Cast Aluminum housing with chemically resistant coating; Polycarbonate cover with Polycarbonate flexible window, Protection IP66/NEMA 4X/CSA Type 3S
