About This Product
■GroLine series for agriculture and hydroponic cultivation
The GroLine series was created for agricultural and hydroponic growers. Among them, HI 981421 is a product that can constantly measure and monitor pH/EC/TDS/℃. The main role of conventional wall-mounted devices was to monitor the nutrient solution, but this device has unprecedented functionality and is useful for crop management.
■Applications
Nutrient solution management for hydroponic cultivation in plant factories, greenhouse cultivation, and home gardens, water quality management for aquariums such as goldfish, etc. (Although this series is aimed at agriculture, it can be used in many applications as a pH/EC/TDS/℃ monitor. Masu.)
■Easy to see and understand measurement values
pH, EC (or TDS) and temperature are displayed simultaneously and are backlit so they can be read clearly even in the dark. In addition, the alarm function allows you to set upper and lower limits for each item, and if the value exceeds (below) the set value, the backlight on the screen and the measured value outside the range will flash to notify you.
■Understand movements (trends) in nutrient solution values
HI 981421 automatically saves measurement values. Records data for the past 30 days every 15 minutes. Maximum, minimum, and average values can be viewed at any time, and graphs can also be displayed. This allows you to understand the movement (trend) of the nutrient solution value and consider its causes and countermeasures.
■Calibrate pH and EC at the same time
HI 981421 can calibrate pH and EC simultaneously by using a dedicated pH/EC simple standard solution. Usually, standard solutions are required for pH and EC calibration, but this is a very convenient function that allows you to use only one standard solution. (pH/EC simple standard solution: pH is 6.86pH, EC is 5.00mS/cm)
■Data transfer is also possible.
Data saved on the main unit can be transferred from the main unit to a PC using a USB memory or USB cable. It is displayed in CSV format on a PC and is convenient to manage.
*The USB port of this device is USB-C (Type-C).
■Set contents
Main unit, pH/EC/TDS/℃ electrode (HI 1285-9), 2 bags of pH/EC simple standard solution, 2 bags of electrode cleaning solution, 12VDC adapter, Japanese instruction manual, etc.
