Model NI214 Negative Ion and Alkaline Ion Water Tester Quickly check the ion balance and alkaline condition of drinking water with a compact, handheld tester designed for simple, onthespot water quality checks. The NI214 identifies negative ion presence and alkaline ion characteristics to help you confirm whether water meets your expected ionization profile. Key benefits Know what you are testing: specifically measures negative ion levels and alkaline ion characteristics for clear, focused results. Easy and fast checks: lightweight, portable design enables quick measurements anytime you need a readout. Simple operation: designed for straightforward use so you can test water without technical training. Practical for everyday decisions: use it to verify bottled water, ionizer output, and filter performance. Main features and attributes Function: Detects negative ions and evaluates alkaline ion properties in water. Model NI214. Compatibility: Suitable for testing bottled water, tap water, water from ionizer or alkaline machines, and water after filtration systems. Size and portability: Handheld, compact form factor for convenient storage and travel. Construction: Built for routine use with materials selected for durability and regular contact with water. Performance: Provides rapid, onlocation readings to support frequent monitoring and simple comparisons. How it solves common problems Confirms device output: Verify that home ionizers and alkaline units are producing the expected ionized water without guessing. Monitors filter effectiveness: Check water after filtration to detect changes in ion characteristics that may indicate filter replacement is needed. Validates bottled or source water: Assess whether a water source matches the ion profile you expect before use. Typical use scenarios Home ionizer testing: Place the probe in water from a household ionizer to confirm negative ion presence and alkaline behavior soon after adjustment or installation. Travel and bottled water checks: Carry the compact tester to quickly verify bottled or vending machine water while away from home. Water system maintenance: Use after a filter change or system service to compare results before and after maintenance. What to expect Straightforward, repeatable checks that support routine monitoring and comparison across water sources. A compact tester that fits easily into a drawer or travel bag for convenient access when you need to test. Model NI214 is designed for users who need focused, portable testing of negative ion and alkaline ion characteristics in drinking water.
