BIO energy detection pen — accurate, fast water testing with a copper probe Key benefits More accurate, faster testing: precision copper probe delivers reliable conductivity/energy readings and shorter test times compared with generic probes. Simple, immediate results: builtin light indicator shows mineral water presence — light on for mineral water, off for nonmineral water — so you can tell results at a glance. Broad compatibility: works with energy water machines, functional water machines, ionized water machines, ultrafiltration and RO water purifiers, and alkaline or mineralized energy cups to verify whether water meets expected properties. Practical and portable: penstyle form factor lets you carry and use the device wherever you need a quick check. What it does Rapidly discriminates between plain water, mineral water, and energy water using the BIO energy detection pen's copper probe and indicator light. Helps verify postfiltration/processing quality and confirm that devices producing 'energy' or mineralized water are performing as intended. Important attributes Probe material: precision copper probe for stable, accurate contact and measurement. Indicator: builtin light that illuminates when the device detects mineral water; no light for nonmineral water. Form factor: compact penstyle detector designed for handheld, onthespot checks. Performance: optimized for faster response and clearer discrimination among water types. Use scenarios After installing or servicing an RO or ultrafiltration purifier, quickly confirm output water is of unintended minerals or that mineral/energy functions are operating correctly. Test bottled and tap sources to distinguish mineral water from regular water before use in lab, kitchen, or healthproduct testing. Verify performance of ionized or functional water machines and energy cups in retail, service, or home settings to ensure the device output matches labeled claims. How to use (brief) Insert the copper probe into the water sample. Observe the light indicator: light on indicates mineral water; no light indicates nonmineral/plain water. Interpret results quickly to decide whether further testing or maintenance is needed. This BIO energy detection pen provides a straightforward, accurate way to check the type and quality of water from a wide range of watertreatment and mineralizing devices.
