X2change™ Sensor: pH

pH sensors are used to measure the amount of alkalinity and acidity in bodies of water. AML Oceanographic offers two types of references. The NaCl (Sodium Chloride) Reference is a longer lasting reference electrode in seawater environments which is good for long-term in-situ deployments. The KCl (Potassium Chloride) Reference is better suited for standard profile data collection. It is also commonly used for fresh water applications. Users can choose between two depth ratings (1500 or 6000 m) for either reference. Powered by Idronaut, all X2change™ pH sensors have a range of 1-13, accuracy of ±0.1 pH, resolution of 0.01 pH and a response time of 3 seconds. Please contact the AML Sales team if you are unsure which option is best for your project.

X2change™ is the industry’s leading family of field-swappable sensor heads. Each sensor head contains its own embedded calibration and can be moved from instrument to instrument without impacting accuracy. Changing sensors is easy: simply unscrew one sensor head and replace it with another.

Key Benefits:

• Zero Down Time – With X2•Series sensors, recalibrated sensors are sent to the instrument instead of sending the instrument to the recalibration centre.
• Reduce Logistical Costs – With X2•Series small sensor heads are shipped instead of heavy instruments.
• Increased Flexibility – Field-swappable sensor heads enable any organization – big or small – to become a virtual recalibration centre by stocking spare calibrated sensor heads.
• One Instrument, Multiple Applications – the ability to change sensor type on any instrument to suit specific application requirements. This means instrument duplicates (identical instruments dedicated to different pressure ranges, separate instrument for Turbidity, pH, Chlorophyll, etc) become a thing of the past.
• Improved absolute pressure accuracy – You may choose the best full scale pressure range to suit your deployment depth.

X2change™ sensor heads are used exclusively with X2•Series / Orange Line instrumentation. Total flexibility of instrument model, sensor type, and sensor range ensures that the right instrument is always available. Please refer to the X2•Series brochure for a list of instruments, applications, and specifications.
