תיאור
alpha CON 190
הבקר 190 CON a נועד למדידת ובקרת מוליכות תמיסות.
הבקרה מתבצעת ע"י 2 ממסרים מסוג SPDT
במכשיר 4 לחצנים ו 8 נוריותלחיווי
תחום המדידה,פעולת הממסרים ומצב עבודה.
ניתן לבחור בין שימוש בגשש הטמפרטורה(ATC)
או קביעת טמפרטורה ידנית (מצב MTC), אך במדידת מוליכות מומלץ מאוד להשתמש ברגש טמפרטורה .
חיבור חשמלי כניסת מתח 220V AC
