Manufactured by\u00a0<strong>Lasany International<\/strong>\u00a0under ISO 9001:2015 and WHO-GMP certification in Panchkula, Haryana, the LI-CM4 is trusted by agricultural universities, crop research institutes, government extension departments, and progressive farmers across India and in over 20 countries including Nigeria, Vietnam, Indonesia, Turkey, Brazil, Zimbabwe, Sri Lanka, Philippines, and Kenya. Using advanced optical sensors and dual 2-wavelength concentration difference technology with silicon semiconductor photodiodes, the LI-CM4 measures chlorophyll concentration from 0.0 to 99.9 SPAD and leaf temperature from -10\u00b0C to 99.9\u00b0C \u2014 with \u00b13.0 SPAD accuracy and \u00b10.5\u00b0C temperature accuracy \u2014 in less than 3 seconds per measurement without any leaf damage. Because chlorophyll content and leaf nitrogen content share a direct physiological relationship, the LI-CM4 provides a real-time, on-the-spot nitrogen demand indicator that eliminates guesswork from fertilisation decisions. Its 30KB onboard memory with automatic average calculation, PC software for data management, rechargeable 4.2V Li-ion battery, and 200-gram portable design make the LI-CM4 the comprehensive plant nutrition analysis solution for field-to-laboratory agricultural research and precision crop management worldwide.<\/p>\n<\/div>\n<div class=\"section\">\n<h3 class=\"section-title\"><strong>Key features<\/strong><\/h3>\n<div class=\"features-grid\">\n<ul>\n<li class=\"feat-card star\"><i class=\"ti ti-chart-dots\"><\/i><strong>Advanced optical sensors<\/strong>High-precision calibrated optical sensors deliver consistent, research-grade SPAD measurement accuracy.<\/li>\n<li class=\"feat-card star\"><i class=\"ti ti-leaf\"><\/i><strong>Non-destructive SPAD analysis<\/strong>Measures chlorophyll content non-destructively via 2mm\u00d72mm leaf clamp \u2014 no leaf damage, no sample prep.<\/li>\n<li class=\"feat-card\"><i class=\"ti ti-temperature\"><\/i><strong>Simultaneous leaf temperature<\/strong>Measures -10 to 99.9\u00b0C leaf temperature simultaneously with SPAD for complete plant physiology profiling.<\/li>\n<li class=\"feat-card\"><i class=\"ti ti-bolt\"><\/i><strong>&lt;3-second measurement<\/strong>Sub-3-second reading interval supports rapid high-throughput sampling across large agricultural areas.<\/li>\n<li class=\"feat-card\"><i class=\"ti ti-database\"><\/i><strong>30KB memory + auto average<\/strong>Onboard storage with automatic average SPAD value computation across all stored readings.<\/li>\n<li class=\"feat-card\"><i class=\"ti ti-device-laptop\"><\/i><strong>PC software connectivity<\/strong>Connect to PC for complete data export, record management, trend analysis, and reporting.<\/li>\n<li class=\"feat-card\"><i class=\"ti ti-battery-charging\"><\/i><strong>Rechargeable Li-ion battery<\/strong>4.2V \/ 2000mAh rechargeable battery for extended, uninterrupted full-day field operation.<\/li>\n<li class=\"feat-card\"><i class=\"ti ti-world\"><\/i><strong>Global export instrument<\/strong>Trusted by agronomists and researchers in 20+ countries across Asia, Africa, and South America.<\/li>\n<\/ul>\n<\/div>\n<\/div>\n<div class=\"section\">\n<h3 class=\"section-title\"><strong>Technical specifications<\/strong><\/h3>\n<div>\n<table class=\"specs-table\">\n<tbody>\n<tr>\n<td>Model<\/td>\n<td>LI-CM4<\/td>\n<\/tr>\n<tr>\n<td>Instrument type<\/td>\n<td>Chlorophyll Meter \/ Plant Nutrition Analyzer<\/td>\n<\/tr>\n<tr>\n<td>Measuring area<\/td>\n<td>2 mm \u00d7 2 mm<\/td>\n<\/tr>\n<tr>\n<td>Measuring mode<\/td>\n<td>2-wavelength concentration difference optical method<\/td>\n<\/tr>\n<tr>\n<td>Sensor type<\/td>\n<td>Silicon semiconductor photodiode<\/td>\n<\/tr>\n<tr class=\"hl\">\n<td>Measuring range<\/td>\n<td>0.0 \u2013 99.9 SPAD \u00b7 -10 to 99.9\u00b0C<\/td>\n<\/tr>\n<tr class=\"hl\">\n<td>Accuracy<\/td>\n<td>\u00b1 3.0 SPAD \u00b7 \u00b1 0.5\u00b0C<\/td>\n<\/tr>\n<tr>\n<td>Repeatability<\/td>\n<td>\u00b1 0.3 SPAD \u00b7 \u00b1 0.2\u00b0C<\/td>\n<\/tr>\n<tr class=\"hl\">\n<td>Min. measuring interval<\/td>\n<td>&lt;
