多功能PH計,配有PE-03電極,溫度傳感器,SD存儲卡,校準溶液。附帶的288 pH計是一種易於使用的儀器,用於測量pH,mV及溫度。使用228 pH計,溫度和pH值可以直接以Excel格式存儲在SD卡上,或使用RS-232傳輸到電腦中。


The food pH meter 228M is a very easy to use hand-held pH meter for food. The pH value and the temperature can be read off via the large LCD display or saved to the SD card (Excel file). Another option is the online transmission via the RS-232 interface directly from the pH meter to a PC or laptop. For this, we offer optional software and the appropriate RS-232 interface cable as an accessory.


The temperature compensation is carried out either manually or automatically via the supplied stainless steel temperature sensor. All this allows a fast and reliable pH measurement of all foods, e.g. sausage, meat and cheese. The pH meter has a three-point calibration, which is performed automatically. The pH meter is battery operated (6 x 1.5 V batteries are included). The pH-Meter 228M is ideal for occasional pH measurements in the laboratory.
